Android13 Targeting S+ (version 31 and above) requires that one of FLAG_IMMUTABLE or FLAG_MUTABLE

最近把以前的11的代码移植到13上碰到的问题,记录一下:

Targeting S+ (version 31 and above) requires that one of FLAG_IMMUTABLE or FLAG_MUTABLE be specified when creating a PendingIntent.
    Strongly consider using FLAG_IMMUTABLE, only use FLAG_MUTABLE if some functionality depends on the PendingIntent being mutable, e.g. if it needs to be used with inline replies or bubbles.

错误分析:

错误提示在使用PendingIntent时,无论是创建或使用的时候flags参数要求必须添加 FLAG_IMMUTABLE或者FLAG_MUTABLE的两个之中其中一个,而且官方还强烈推荐使用FLAG_IMMUTABLE(代码不同,依情况而定官方的推荐)。

解决办法如下:

1、在清单文件中所有activity,receiver,service等, 带有intent-filter标签的地方必须添加exported属性

android:exported="true" 

2、修改错误关键代码

        AlarmManager am = (AlarmManager) mContext.getSystemService(Context.ALARM_SERVICE);
        Intent intent = createTimerSwitchIntent(mContext, timerSwitch,
                TimerSwitchConstants.ACTION_POWER_OFF);
        //用法错误处
        // PendingIntent pendingIntent = PendingIntent.getBroadcast(mContext, 0,
        //         intent, PendingIntent.FLAG_UPDATE_CURRENT);

        //start 修改后
        PendingIntent pendingIntent;
        if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.S) {
            pendingIntent = PendingIntent.getBroadcast(mContext, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT | PendingIntent.FLAG_IMMUTABLE);
        } else {
            pendingIntent = PendingIntent.getBroadcast(mContext, 0, intent, PendingIntent.FLAG_ONE_SHOT);
        }
        //end

        LogFormatTime(timerSwitch.switchtime, "OFF");
        am.setExact(AlarmManager.RTC_WAKEUP, timerSwitch.switchtime, pendingIntent);
