Android USB海量存储弹出

Question

我想创建一个弹出窗口，当一个USB海量存储设备连接到设备。我正在尝试使用ACTION_MEDIA_MOUNTED。我能够看到ACTION_MEDIA_MOUNTED正在通过日志，但我的应用程序不会弹出。 这是我的代码。
在此先感谢...

MemStickReciever.class

public class MemStickReciever extends BroadcastReceiver { 
public final String TAG = "usbfile"; 
@Override 
public void onReceive(Context context, Intent intent) { 
    if (intent.getAction().equals(intent.ACTION_MEDIA_MOUNTED)) 
     { 

     Log.d(TAG,"USB MOUNTED (1)"); 
     Intent intentLaunch = new Intent(context,FileExplore.class); 
     Log.d(TAG,"intent has been created "); 
     context.startActivity(intentLaunch); 
     Log.d(TAG,"intent launched "); 
    } 

} 

FileExplore.class

public class FileExplore extends Activity { 
@Override 
protected void onCreate(Bundle savedInstanceState) { 
    // TODO Auto-generated method stub 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.main); 
} 
} 

的Manifest.xml

Answer 1

我刚刚从提取getExternalStorageState（意图开始活动）作品

public class MemStickReciever extends BroadcastReceiver { 
     public final String TAG = "usbfile"; 
     @Override 
     public void onReceive(Context context, Intent intent) { 

    //As through the logs when the usb mass storage is connected **sendStorageIntent Intent { act=android.intent.action.MEDIA_MOUNTED** was displayed in the log 

    if(Environment.getExternalStorageState().equals(Environment.MEDIA_MOUNTED)){ 

       onMemcardMounted(); 
       Log.d(TAG,"USB MOUNTED (1)"); 
       Intent intentLaunch = new Intent(context,FileExplore.class); 
       intentLaunch.addFlags(Intent.FLAG_FROM_BACKGROUND); 
       intentLaunch.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); 
       Log.d(TAG,"intent has been created "); 
       context.startActivity(intentLaunch); 
       Log.d(TAG,"intent launched "); 
      } 

     } 

Answer 2

你可以尝试，而不是intent.getAction（）和代码从BroadcastReceiver

Intent intent = new Intent(context,FileExplore.class); 
intent.addFlags(Intent.FLAG_FROM_BACKGROUND); 
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); 
context.startActivity(intent);
