如何使用BatteryStatsHelper获取应用程序电池信息？

Question

当我使用BatteryStatsHelper得到应用的电池信息来源，我已经设置了权限“android.permission.BATTERY_STATS”，但系统说我没有权限。

Caused by: java.lang.SecurityException: uid 10164 does not have android.permission.BATTERY_STATS.

在这里尝试这样的事情，摆脱Batstat方法。 也在这里检查http://www.tutorialforandroid.com/2009/01/getting-battery-information-on-android.html

这应该会给你所有的信息，你想监测一个棉絮。

public class Main extends Activity { 
private TextView batteryTxt; 
private BroadcastReceiver mBatInfoReceiver = new BroadcastReceiver(){ 
@Override 
public void onReceive(Context ctxt, Intent intent) { 
    int level = intent.getIntExtra(BatteryManager.EXTRA_LEVEL, 0); 
    batteryTxt.setText(String.valueOf(level) + "%"); 
} 
}; 

@Override 
public void onCreate(Bundle b) { 
super.onCreate(b); 
setContentView(R.layout.main); 
batteryTxt = (TextView) this.findViewById(R.id.batteryTxt); 
this.registerReceiver(this.mBatInfoReceiver, new IntentFilter(Intent.ACTION_BATTERY_CHANGED)); 
} 
}
