Question

我遇到了通过短信发送坐标的应用程序的问题。当我添加电池电量时，应用程序在捕获修复后停止工作。（坐标不显示，但它们是通过短信。）

请帮忙。

Answer 1

尝试在代码中添加android.permission.BATTERY_STATS权限。

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

Answer 2

// 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" />
