首先整理思路,先思考实现逻辑:
1.集成信鸽推送
2.实现自定义推送
3.在自定义推送中,接收推送的方法内启动强制退出功能。
思路逻辑很简单,但是实现起来就得一步一步做,先集成信鸽:
这里主要是参考官方开发文档即可
然后是实现自定义推送接受方,即自定义receiver
CustomReceiver.java
/** * */import u.upd.l;import android.content.Context;import android.content.Intent;import com.dhcc.gpscarmanager_phone.CustomServices.ForceOfflineService;import com.dhcc.gpscarmanager_phone.Util.L;import com.tencent.android.tpush.XGPushBaseReceiver;import com.tencent.android.tpush.XGPushClickedResult;import com.tencent.android.tpush.XGPushRegisterResult;import com.tencent.android.tpush.XGPushShowedResult;import com.tencent.android.tpush.XGPushTextMessage;public class CustomReceiver extends XGPushBaseReceiver { /* * (non-Javadoc) * * @see * com.tencent.android.tpush.XGPushBaseReceiver#onDeleteTagResult(android * .content.Context, int, java.lang.String) */ @Override public void onDeleteTagResult(Context context, int arg1, String arg2) { // TODO Auto-generated method stub } /* * (non-Javadoc) * * @see * com.tencent.android.tpush.XGPushBaseReceiver#onNotifactionClickedResult * (android.content.Context, com.tencent.android.tpush.XGPushClickedResult) */ @Override public void onNotifactionClickedResult(Context context, XGPushClickedResult arg1) { // TODO Auto-generated method stub } /* * (non-Javadoc) * * @see * com.tencent.android.tpush.XGPushBaseReceiver#onNotifactionShowedResult * (android.content.Context, com.tencent.android.tpush.XGPushShowedResult) */ @Override public void onNotifactionShowedResult(Context context, XGPushShowedResult result) { // TODO Auto-generated method stub // 这里是测试代码,在接受到“下线”这两个字后,接收通知的应用强行下线 if ("下线".equals(result.getContent())) { L.e(result.getContent()); context.getApplicationContext().startService(new Intent(context.getApplicationContext(), ForceOfflineService.class)); } } /* * (non-Javadoc) * * @see * com.tencent.android.tpush.XGPushBaseReceiver#onRegisterResult(android * .content.Context, int, com.tencent.android.tpush.XGPushRegisterResult) */ @Override public void onRegisterResult(Context context, int arg1, XGPushRegisterResult arg2) { // TODO Auto-generated method stub } /* * (non-Javadoc) * * @see * com.tencent.android.tpush.XGPushBaseReceiver#onSetTagResult(android.content * .Context, int, java.lang.String) */ @Override public void onSetTagResult(Context context, int arg1, String arg2) { // TODO Auto-generated method stub } /* * (non-Javadoc) * * @see * com.tencent.android.tpush.XGPushBaseReceiver#onTextMessage(android.content * .Context, com.tencent.android.tpush.XGPushTextMessage) */ @Override public void onTextMessage(Context context, XGPushTextMessage message) { // TODO Auto-generated method stub } /* * (non-Javadoc) * * @see * com.tencent.android.tpush.XGPushBaseReceiver#onUnregisterResult(android * .content.Context, int) */ @Override public void onUnregisterResult(Context context, int arg1) { // TODO Auto-generated method stub }}
在注册文件中加入该Revceiver的静态注册代码:
<receiver android:name="CustomReceivers.CustomReceiver" > <intent-filter> <!-- 接收消息透传 --> <action android:name="com.tencent.android.tpush.action.PUSH_MESSAGE" /> <!-- 监听注册、反注册、设置/删除标签、通知被点击等处理结果 --> <action android:name="com.tencent.android.tpush.action.FEEDBACK" /> </intent-filter> </receiver>
然后注意这句代码:
if ("下线".equals(result.getContent())) { L.e(result.getContent()); context.getApplicationContext().startService(new Intent(context.getApplicationContext(), ForceOfflineService.class)); }由于目前是测试代码,所以我判断的是如果服务端发送的是“下线”的话,我就将该设备强制下线,在实际开发的过程中,其流程应当是
用户登录-> 判断当前的Token与数据库中存储的Token是否一致-> 如果不一致,则对数据库中的Token的用户发送约定好的下线通知,可以是参数也可以是字符串-> 手机端接到下线通知后,强制下线-> 服务端将新的Token保存到数据库中去,老的Token销毁
/** * */import com.dhcc.gpscarmanager_phone.CustomReceivers.ForceOfflineReceiver;import com.dhcc.gpscarmanager_phone.Util.L;import u.upd.l;import android.app.Service;import android.content.Intent;import android.content.IntentFilter;import android.os.IBinder;import android.util.Log;public class ForceOfflineService extends Service { private static final String TAG = "ForceOfflineService"; ForceOfflineReceiver forceOfflineReceiver; @Override public void onCreate() { Log.i(TAG, "ExampleService-onCreate"); super.onCreate(); IntentFilter intentFilter=new IntentFilter(); intentFilter.addAction("com.dhcc.AppOffline"); forceOfflineReceiver=new ForceOfflineReceiver(); registerReceiver(forceOfflineReceiver, intentFilter); Intent intent =new Intent("com.dhcc.AppOffline"); getApplicationContext().sendBroadcast(intent); } @Override public void onStart(Intent intent, int startId) { Log.i(TAG, "ExampleService-onStart"); super.onStart(intent, startId); } @Override public int onStartCommand(Intent intent, int flags, int startId) { //执行文件的下载或者播放等操作 Log.i(TAG, "ExampleService-onStartCommand"); /* * 这里返回状态有三个值,分别是: * 1、START_STICKY:当服务进程在运行时被杀死,系统将会把它置为started状态,但是不保存其传递的Intent对象,之后,系统会尝试重新创建服务; * 2、START_NOT_STICKY:当服务进程在运行时被杀死,并且没有新的Intent对象传递过来的话,系统将会把它置为started状态, * 但是系统不会重新创建服务,直到startService(Intent intent)方法再次被调用; * 3、START_REDELIVER_INTENT:当服务进程在运行时被杀死,它将会在隔一段时间后自动创建,并且最后一个传递的Intent对象将会再次传递过来。 */ return super.onStartCommand(intent, flags, startId); } @Override public IBinder onBind(Intent intent) { Log.i(TAG, "ExampleService-onBind"); return null; } @Override public void onDestroy() { Log.i(TAG, "ExampleService-onDestroy"); super.onDestroy(); unregisterReceiver(forceOfflineReceiver); } }
别忘了在配置文件中加入Service的注册:
<!-- 强制下线服务 --> <service android:name="com.dhcc.gpscarmanager_phone.CustomServices.ForceOfflineService"/>在OnCreate方法中加入了启动强制下线的Receiver的代码:
IntentFilter intentFilter = new IntentFilter(); intentFilter.addAction("com.dhcc.AppOffline"); forceOfflineReceiver = new ForceOfflineReceiver(); registerReceiver(forceOfflineReceiver, intentFilter); Intent intent = new Intent("com.dhcc.AppOffline"); getApplicationContext().sendBroadcast(intent);
这里要注意的是,不能直接用Context进行启动下线Receiver的操作,否则会报错:
IntentReceiver components are not allowed to register to receive intents
必须利用getApplicationContext的方式动态注册ForceOfflineRecevier(),不能用静态注册的方式,否则也会报上边同样的错误(但是这里不知道为什么)
具体解决原因参照:http://blog.csdn.net/eimsteim/article/details/7220920
然后启动这个ForceOfflineReceiver,他的内容是这样的:
import com.baidu.navisdk.util.common.Stopwatch;import com.dhcc.gpscarmanager_phone.CustomServices.ForceOfflineService;import com.dhcc.gpscarmanager_phone.CustomView.ActivityCollector;import com.dhcc.gpscarmanager_phone.Module.Welcome.WelcomPage.LoginActivity;import android.app.AlertDialog;import android.content.BroadcastReceiver;import android.content.Context;import android.content.DialogInterface;import android.content.DialogInterface.OnClickListener;import android.content.Intent;import android.view.WindowManager;public class ForceOfflineReceiver extends BroadcastReceiver { /* * (non-Javadoc) * * @see android.content.BroadcastReceiver#onReceive(android.content.Context, * android.content.Intent) */ @Override public void onReceive(final Context context, Intent intent) { // TODO Auto-generated method stub intent = new Intent(context, ForceOfflineService.class); context.stopService(intent); AlertDialog.Builder dialogBuilder = new AlertDialog.Builder(context); dialogBuilder.setTitle("已下线"); dialogBuilder.setMessage("您的账户已在另一个设备登录,请尝试重新登陆"); dialogBuilder.setCancelable(false); dialogBuilder.setPositiveButton("登 录", new OnClickListener() { @Override public void onClick(DialogInterface arg0, int arg1) { // TODO Auto-generated method stub ActivityCollector.finishAll(); Intent intent = new Intent(context, LoginActivity.class); intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); context.startActivity(intent); } }); AlertDialog alertDialog = dialogBuilder.create(); alertDialog.getWindow().setType( WindowManager.LayoutParams.TYPE_SYSTEM_ALERT); alertDialog.show(); }}
启动一个窗口,告诉用户你的账户在其他设备登录了,然后强制启动登录界面,并把之前启动的Activity都关闭掉,所以这里的关键类就是
ActivityCollector了:
import java.util.ArrayList;import java.util.List;import android.app.Activity;public class ActivityCollector { public static List<Activity> activities=new ArrayList<Activity>(); public static void addActivity(Activity activity){ activities.add(activity); } public static void removeActivity(Activity activity){ activities.remove(activity); } public static void finishAll(){ for(Activity activity:activities){ if(activity.isFinishing()){ activity.finish(); } } }}
功能自己看,然后就是在你的基类BaseActivity里加入对应的代码:
@Override public void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState); ActivityCollector.addActivity(this);}protected void onDestroy(){ super.onDestroy(); ActivityCollector.removeActivity(this); }
这样就把新启动的Activity管理起来了,然后在关闭的时候利用循环关闭对应的Activity即可了。
由于使用的是系统的弹出窗口,所以要在配置文件中加入这么一句权限:
<uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW" />
