最近到4412最基本的都调了 然后觉得没事做了 所以增加一个HDMI的设置 不能闲着
以下使用的是广州斯道的icool210开发板 源码修改如下
最开始我是先在设置里加上这些设置然后在去实现功能 这里就一起说了 之前android2.3里有HDMI设置所以这里就参照那个增加 首先修改Setting
查看libhdmi库首先查看下hdmi能设置的格式 源码路径
device/samsung/common/s5p/libhdmi/SecHdmi.cpp
你会发现有如下代码
mHdmiResolutionValueList[0] = 1080960; mHdmiResolutionValueList[1] = 1080950; mHdmiResolutionValueList[2] = 1080930; mHdmiResolutionValueList[3] = 1080160; mHdmiResolutionValueList[4] = 1080150; mHdmiResolutionValueList[5] = 720960; mHdmiResolutionValueList[6] = 720950; mHdmiResolutionValueList[7] = 5769501; mHdmiResolutionValueList[8] = 5769502; mHdmiResolutionValueList[9] = 4809601; mHdmiResolutionValueList[10] = 4809602;ResolutionValue根据这个我们大致知道了支持了格式 下面来修改Setting
源码路径 packages/apps/Settings/res/values/arrays.xml
增加如下代码
<!-- TV Out settings. --> <string-array name="tv_resolution_entries"> <item>1080P_60</item> <item>1080P_50</item> <item>1080P_30</item> <item>1080I_60</item> <item>1080I_50</item> <item>720P_60</item> <item>720P_50</item> <item>576P_50_16_9</item> <item>576P_50_4_3</item> <item>480P_60_16_9</item> <item>480P_60_4_3</item> </string-array> <!-- Do not translate. --> <string-array name="tv_resolution_values" translatable="false"> <!-- Do not translate. --> <item>1080960</item> <!-- Do not translate. --> <item>1080950</item> <!-- Do not translate. --> <item>1080930</item> <!-- Do not translate. --> <item>1080160</item> <!-- Do not translate. --> <item>1080150</item> <!-- Do not translate. --> <item>720960</item> <!-- Do not translate. --> <item>720950</item> <!-- Do not translate. --> <item>5769501</item> <!-- Do not translate. --> <item>5769502</item> <!-- Do not translate. --> <item>4809601</item> <!-- Do not translate. --> <item>4809602</item> </string-array> <!-- TV Out settings. --> <string-array name="tv_hdcp_entries"> <item>Disable</item> <item>Enable</item> </string-array> <!-- Do not translate. --> <string-array name="tv_hdcp_values" translatable="false"> <!-- Do not translate. --> <item>0</item> <!-- Do not translate. --> <item>1</item> </string-array> <!-- TV Out settings. --> <string-array name="tv_mode_entries"> <item>HDMI(YCbCr)</item> <item>HDMI(RGB)</item> <item>DVI</item> </string-array> <!-- Do not translate. --> <string-array name="tv_mode_values" translatable="false"> <!-- Do not translate. --> <item>0</item> <!-- Do not translate. --> <item>1</item> <!-- Do not translate. --> <item>2</item> </string-array>源码路径 packages/apps/Settings/res/values/strings.xml
增加如下内容
<!-- Sound & display settings screen, setting option name to change TV Mode --> <string name="tv_mode">TV Mode</string> <!-- Sound & display settings screen, setting option summary to change TV Mode --> <string name="tv_mode_summary">Choose TV out mode</string> <!-- Sound & display settings screen, setting option name to change TV Resolution --> <string name="tv_resolution">TV Resolution</string> <!-- Sound & display settings screen, setting option summary to change TV Resolution --> <string name="tv_resolution_summary">Choose TV resolution</string> <!-- Sound & display settings screen, setting option name to change TV HDCP --> <string name="tv_hdcp">TV HDCP</string> <!-- Sound & display settings screen, setting option summary to change TV HDCP --> <string name="tv_hdcp_summary">Enable HDMI HDCP</string>源码路径 packages/apps/Settings/res/xml/display_settings.xml
增加如下内容
<ListPreference android:key="tv_mode" android:title="@string/tv_mode" android:summary="@string/tv_mode_summary" android:persistent="false" android:entries="@array/tv_mode_entries" android:entryValues="@array/tv_mode_values" /> <ListPreference android:key="tv_resolution" android:title="@string/tv_resolution" android:summary="@string/tv_resolution_summary" android:persistent="false" android:entries="@array/tv_resolution_entries" android:entryValues="@array/tv_resolution_values" /> <ListPreference android:key="tv_hdcp" android:title="@string/tv_hdcp" android:summary="@string/tv_hdcp_summary" android:persistent="false" android:entries="@array/tv_hdcp_entries" android:entryValues="@array/tv_hdcp_values" />接着修改framework
源码路径:frameworks/base/core/java/android/provider/Settings.java
增加如下内容:
/** * The tv out mode. */ public static final String TV_MODE = "tv_mode"; /** * The tv out resolution. */ public static final String TV_RESOLUTION = "tv_resolution"; /** * The tv out mode. */ public static final String TV_HDCP = "tv_hdcp";接着在这个文件里搜所SCREEN_OFF_TIMEOUT
会在public static final String[] SETTINGS_TO_BACKUP这个数组里找到一个 然后在它下面增加如下
TV_MODE, TV_RESOLUTION, TV_HDCP,按照我的理解这里应该是用来保存数据到数据库的 然后系统再次启动后设置还能保存
接着增加调用hdmi相关函数的接口 这里我是直接把2.3的拷过来然后进行的修改
创建相应目录增加以下文件frameworks/base/slsi/java/com/slsi/sec/android/HdmiService.java
内容如下
package com.slsi.sec.android;public class HdmiService{ static { System.loadLibrary("hdmiservice_jni"); } public native void setHdmiCableStatus(int status); public native void setHdmiMode(int mode); public native void setHdmiResolution(int resolution); public native void setHdmiHdcp(int enHdcp); public native void initHdmiService();}增加以下文件frameworks/base/slsi/jni/Android.mk内容如下
LOCAL_PATH:= $(call my-dir)include $(CLEAR_VARS)LOCAL_SRC_FILES:= \ com_slsi_sec_android_HdmiService.cpp \ onload.cppLOCAL_C_INCLUDES += \ $(JNI_H_INCLUDE)LOCAL_SHARED_LIBRARIES := \ libcutils \ libandroid_runtime \ libnativehelperifeq ($(S5P_BOARD_USES_HDMI),true)LOCAL_C_INCLUDES += \ device/samsung/common/s5p/libhdmiLOCAL_SHARED_LIBRARIES += libhdmiclientLOCAL_CFLAGS += -DBOARD_USES_HDMIendifLOCAL_PRELINK_MODULE := falseifeq ($(TARGET_SIMULATOR),true)ifeq ($(TARGET_OS),linux)ifeq ($(TARGET_ARCH),x86)LOCAL_LDLIBS += -lpthread -ldl -lrtendifendifendififeq ($(WITH_MALLOC_LEAK_CHECK),true) LOCAL_CFLAGS += -DMALLOC_LEAK_CHECKendifLOCAL_MODULE_TAGS := optional engLOCAL_MODULE:= libhdmiservice_jniinclude $(BUILD_SHARED_LIBRARY)增加以下文件frameworks/base/slsi/jni/com_slsi_sec_android_HdmiService.cpp
内容如下
#define LOG_TAG "HDMIStatusService"#include "jni.h"#include "JNIHelp.h"#include <cutils/log.h>#if defined(BOARD_USES_HDMI)#include "SecHdmiClient.h"#endifnamespace android {/* * Class: com_slsi_sec_android_HdmiService * Method: setHdmiCableStatus * Signature: (I)V */static void com_slsi_sec_android_HdmiService_setHdmiCableStatus (JNIEnv *env, jobject obj, jint i){ int result = 0;#if defined(BOARD_USES_HDMI) //LOGD("%s HDMI status: %d", __func__, i); (SecHdmiClient::getInstance())->setHdmiCableStatus(i);#else return;#endif //return result;}/* * Class: com_slsi_sec_android_setHdmiMode * Method: setHdmiMode * Signature: (I)V */static void com_slsi_sec_android_HdmiService_setHdmiMode (JNIEnv *env, jobject obj, jint i){ int result = 0;#if defined(BOARD_USES_HDMI) (SecHdmiClient::getInstance())->setHdmiMode(i);#else return;#endif}/* * Class: com_slsi_sec_android_setHdmiResolution * Method: setHdmiResolution * Signature: (I)V */static void com_slsi_sec_android_HdmiService_setHdmiResolution(JNIEnv *env, jobject obj, jint i){ int result = 0;#if defined(BOARD_USES_HDMI) (SecHdmiClient::getInstance())->setHdmiResolution(i);#else return;#endif}/* * Class: com_slsi_sec_android_setHdmiHdcp * Method: setHdmiHdcp * Signature: (I)V */static void com_slsi_sec_android_HdmiService_setHdmiHdcp(JNIEnv *env, jobject obj, jint i){ int result = 0;#if defined(BOARD_USES_HDMI) (SecHdmiClient::getInstance())->setHdmiHdcp(i);#else return;#endif}/* * Class: com_slsi_sec_android_HdmiService * Method: initHdmiService * Signature: ()V */static void com_slsi_sec_android_HdmiService_initHdmiService (JNIEnv *env, jobject obj){#if defined(BOARD_USES_HDMI) LOGI("%s ", __func__); //(SecHdmiClient::getInstance())->init();#else return;#endif //return result;}static JNINativeMethod gMethods[] = { {"setHdmiCableStatus", "(I)V", (void*)com_slsi_sec_android_HdmiService_setHdmiCableStatus}, {"setHdmiMode", "(I)V", (void*)com_slsi_sec_android_HdmiService_setHdmiMode}, {"setHdmiResolution", "(I)V", (void*)com_slsi_sec_android_HdmiService_setHdmiResolution}, {"setHdmiHdcp", "(I)V", (void*)com_slsi_sec_android_HdmiService_setHdmiHdcp}, {"initHdmiService", "()V", (void*)com_slsi_sec_android_HdmiService_initHdmiService},};int register_com_samsung_sec_android_HdmiService(JNIEnv* env){ jclass clazz = env->FindClass("com/slsi/sec/android/HdmiService"); if (clazz == NULL) { LOGE("Can't find com/slsi/sec/android/HdmiService"); return -1; } return jniRegisterNativeMethods(env, "com/slsi/sec/android/HdmiService", gMethods, NELEM(gMethods));}} /* namespace android */增加如下文件:frameworks/base/slsi/jni/onload.cpp内容如下
#include "JNIHelp.h"#include "jni.h"#include "utils/Log.h"#include "utils/misc.h"namespace android {int register_com_samsung_sec_android_HdmiService(JNIEnv* env);};using namespace android;extern "C" jint JNI_OnLoad(JavaVM* vm, void* reserved){ JNIEnv* env = NULL; jint result = -1; if (vm->GetEnv((void**) &env, JNI_VERSION_1_4) != JNI_OK) { LOGE("GetEnv failed!"); return result; } LOG_ASSERT(env, "Could not retrieve the env!"); if(register_com_samsung_sec_android_HdmiService(env) == -1) LOGE("%s register_com_samsung_sec_android_HdmiStatus is failed", __func__); return JNI_VERSION_1_4;}然后修改build/core/pathmap.mk在FRAMEWORKS_BASE_SUBDIRS里增加slsi \
我们要让他启动的时候能能自动设置成设置的参数所以
接着修改frameworks/base/services/java/com/android/server/SystemServer.java
增加如下内容
import com.slsi.sec.android.HdmiService;import static android.provider.Settings.System.TV_MODE;import static android.provider.Settings.System.TV_RESOLUTION;import static android.provider.Settings.System.TV_HDCP;
private HdmiService mHdmiService;然后在
mContentResolver = context.getContentResolver();之后增加如下代码
Slog.i(TAG, "HDMI Setting"); mHdmiService = new HdmiService(); mHdmiService.setHdmiMode(Settings.System.getInt(mContentResolver, TV_MODE, 0)); mHdmiService.setHdmiResolution(Settings.System.getInt(mContentResolver, TV_RESOLUTION, 4809601)); mHdmiService.setHdmiHdcp(Settings.System.getInt(mContentResolver, TV_HDCP, 0));跟着最后修改Setting里的DisplaySetting
源码路径packages/apps/Settings/src/com/android/settings/DisplaySettings.java
增加如下内容
import com.slsi.sec.android.HdmiService;import static android.provider.Settings.System.TV_MODE;import static android.provider.Settings.System.TV_RESOLUTION;import static android.provider.Settings.System.TV_HDCP;
private static final String KEY_TV_MODE = "tv_mode"; private static final String KEY_TV_RESOLUTION = "tv_resolution"; private static final String KEY_TV_HDCP = "tv_hdcp"; private static final int FALLBACK_TV_MODE_VALUE = 0; private static final int FALLBACK_TV_RESOLUTION_VALUE = 4809601; private static final int FALLBACK_TV_HDCP_VALUE = 0; private HdmiService mHdmiService;然后在onCreate增加如下代码
ListPreference tvModePreference = (ListPreference) findPreference(KEY_TV_MODE); tvModePreference.setValue(String.valueOf(Settings.System.getInt( resolver, TV_MODE, FALLBACK_TV_MODE_VALUE))); tvModePreference.setOnPreferenceChangeListener(this); ListPreference tvResolutionPreference = (ListPreference) findPreference(KEY_TV_RESOLUTION); tvResolutionPreference.setValue(String.valueOf(Settings.System.getInt( resolver, TV_RESOLUTION, FALLBACK_TV_RESOLUTION_VALUE))); tvResolutionPreference.setOnPreferenceChangeListener(this); ListPreference tvHdcpPreference = (ListPreference) findPreference(KEY_TV_HDCP); tvHdcpPreference.setValue(String.valueOf(Settings.System.getInt( resolver, TV_HDCP, FALLBACK_TV_HDCP_VALUE))); tvHdcpPreference.setOnPreferenceChangeListener(this); mHdmiService = new HdmiService();接着在onPreferenceChange函数里增加如下内容
if (KEY_TV_MODE.equals(key)) { int value = Integer.parseInt((String) objValue); try { Settings.System.putInt(getContentResolver(), TV_MODE, value); } catch (NumberFormatException e) { Log.e(TAG, "could not persist tv mode setting", e); } mHdmiService.setHdmiMode(value); } if (KEY_TV_RESOLUTION.equals(key)) { int value = Integer.parseInt((String) objValue); try { Settings.System.putInt(getContentResolver(), TV_RESOLUTION, value); } catch (NumberFormatException e) { Log.e(TAG, "could not persist tv resolution setting", e); } mHdmiService.setHdmiResolution(value); }if (KEY_TV_HDCP.equals(key)) { int value = Integer.parseInt((String) objValue); try { Settings.System.putInt(getContentResolver(), TV_HDCP, value); } catch (NumberFormatException e) { Log.e(TAG, "could not persist tv resolution setting", e); } mHdmiService.setHdmiHdcp(value); }基本上就搞定了 最后如图所示
相关patch我也上传到了我的资源 不知道为啥没显示出来 需要的可以去下载
