android - 如何以编程方式关闭棉花糖设备中特定应用程序的打盹模式

Question

Marshmallow API 与以前的 android OS 非常不同。当屏幕关闭时，设备处于打盹模式并且无法同步网络。因此，为了使用网络进行后台操作，我们必须防止打瞌睡模式。

Answer 1

将以下权限添加到 manifest.xml

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

调用下面的方法

public void turnOffDozeMode(Context context){  //you can use with or without passing context
        if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
            Intent intent = new Intent();
            String packageName = context.getPackageName();
            PowerManager pm = (PowerManager) context.getSystemService(Context.POWER_SERVICE);
            if (pm.isIgnoringBatteryOptimizations(packageName)) // if you want to desable doze mode for this package
                intent.setAction(Settings.ACTION_IGNORE_BATTERY_OPTIMIZATION_SETTINGS);
            else { // if you want to enable doze mode
                intent.setAction(Settings.ACTION_REQUEST_IGNORE_BATTERY_OPTIMIZATIONS);
                intent.setData(Uri.parse("package:" + packageName));
            }
            context.startActivity(intent);
        }
    }

或者您也可以使用以下场景...

以编程方式将 Android 应用程序列入白名单可以按如下方式完成：

boolean isIgnoringBatteryOptimizations = pm.isIgnoringBatteryOptimizations(getPackageName());
if(!isIgnoringBatteryOptimizations){
    Intent intent = new Intent();
    intent.setAction(Settings.ACTION_REQUEST_IGNORE_BATTERY_OPTIMIZATIONS);
    intent.setData(Uri.parse("package:" + getPackageName()));
    startActivityForResult(intent, MY_IGNORE_OPTIMIZATION_REQUEST);
}

上面这个activity的启动结果可以通过下面的代码来验证：

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == MY_IGNORE_OPTIMIZATION_REQUEST) {
        PowerManager pm = (PowerManager)getSystemService(Context.POWER_SERVICE);
        boolean isIgnoringBatteryOptimizations = pm.isIgnoringBatteryOptimizations(getPackageName());
        if(isIgnoringBatteryOptimizations){
            // Ignoring battery optimization
        }else{
           // Not ignoring battery optimization
        }
    }
}
