Android電池電量

我通過短信發送座標的應用程序有問題。當我添加電池電量時，捕捉修復程序後應用程序停止工作。（座標不在顯示，但他們是通過短信。）Android電池電量

請幫助。

嘗試添加android.permission.BATTERY_STATS權限代碼。

<uses-permission android:name="android.permission.BATTERY_STATS" />

謝謝，它幫助，但不顯示在屏幕上的座標。當手機在那裏修復一秒鐘並隨着電池電量的文本消失。 – Bart 2012-07-08 16:02:05

// Put this Code into your MainActivity where you want to show level 

private BroadcastReceiver mBatInfoReceiver = new BroadcastReceiver() { 
    @Override 
    public void onReceive(Context c, Intent i) { 
     int level = i.getIntExtra("level", 0); 
     ProgressBar pb = (ProgressBar) findViewById(R.id.progressbar); 
     pb.setProgress(level); 
     TextView tv = (TextView) findViewById(R.id.textfield); 
     tv.setText("Battery Level: " + Integer.toString(level) + "%"); 
    } 

}; 

/** Called when the activity is first created. */ 
@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.main); 
    registerReceiver(mBatInfoReceiver, new IntentFilter(
      Intent.ACTION_BATTERY_CHANGED)); 
} 
// Please Add the given below code into manifest: 

<uses-permission android:name="android.permission.BATTERY_STATS" />
