如何以编程方式关闭棉花糖设备中特定应用的打盹模式

Question

Marshmallow API与以前的Android OS非常不同。屏幕关闭时，设备处于打盹模式且无法同步网络。因此，对于使用网络进行后台操作，我们必须防止打盹模式。

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);
        }
    }

或者您也可以在以下情况下使用...

可以通过编程将Android应用程序列入白名单的步骤如下：

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);
}

可以通过以下代码验证开始以上活动的结果：

@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
        }
    }
}
