一、错误：Unknown host api.tudou.com, throwing UnknownHostException。
????? 解决办法：在AndroidManifest.xml中添加<uses-permission android:name="android.permission.INTERNET" />
二、Unable to find explicit activity class? have you declared this activity in your AndroidManifest.xml?
???? 解决办法：在AndroidManifest.xml的application段添加声明：<activity android:name=".ActivityName" />,详情见：
??????????????????? http://stackoverflow.com/questions/736571/using-intent-in-an-android-application-to-show-another-activity
三、ListActivity setContentView错误：
代码及相关xml如下：
main.xml:
<ListView android:id="@+id/list"
??????????? android:layout_width="fill_parent"
??????????? android:layout_height="fill_parent"
??????????? android:drawSelectorOnTop="false"/>
tudouPlayer.java:
public class tudouPlayer extends ListActivity implements OnClickListener {???
??? /** Called when the activity is first created. */
??? @Override
??? public void onCreate(Bundle savedInstanceState) {
??????? super.onCreate(savedInstanceState);
??????? setContentView(R.layout.main);
??? }
}
编译不会报错，运行时，adb打出来的错误为：
E/AndroidRuntime(? 701): java.lang.RuntimeException: Unable to start activity ComponentInfo{com.java.tudouPlayer/com.java.tudouPlayer.tudouPlayer}: java.lang.RuntimeException: Your content must have a ListView whose id attribute is 'android.R.id.list'
解决办法：
将main.xml中，上面贴出来的那段改为（原因见注释）：
??????? <!-- Here is the list. Since we are using a ListActivity, we
???????????? have to call it "@android:id/list" so ListActivity will
???????????? find it -->
???????
??????? <ListView android:id="@android:id/list"
??????????? android:layout_width="fill_parent"
??????????? android:layout_height="fill_parent"
??????????? android:drawSelectorOnTop="false"/>
四、adb push错误
mksdcard 1024M sdcard1.iso
adb push android.jpg /sdcard/android.jpg
error:failed to copy 'android.jpg' to '/sdcard/android.jpg': Read-only file system
解决办法：
删除sdcard1.iso；
mksdcard 1024M sdcard
adb push android.jpg /sdcard/android.jpg
