Android 13下精确闹钟无法唤醒启动应用的问题求助

正在为Android 13更新应用，该应用依赖精确闹钟功能：用户启用闹钟后，设备需在设定时间唤醒并自动启动应用。因时间精度要求极高，使用setExactAndAllowWhileIdle()函数配置闹钟。

该功能在旧版Android上运行正常，但在三星Android 13设备上，闹钟无法唤醒设备并启动应用。已开启应用的「闹钟和提醒」权限，且将电池使用设置为无限制，问题仍未解决。

代码实现（C++Builder，SDK33） #

_di_JIntent Intent=TJIntent::Create();
_di_JPendingIntent PendingIntent;
        
Intent->setClassName(TAndroidHelper::Context, StringToJString("com.embarcadero.firemonkey.FMXNativeActivity"));
if(VERSION_ANDROID<12)
    PendingIntent = TJPendingIntent::JavaClass->getActivity(TAndroidHelper::Context, 1, Intent, 0);
else
    PendingIntent = TJPendingIntent::JavaClass->getActivity(TAndroidHelper::Context, 1, Intent, TJPendingIntent::JavaClass->FLAG_IMMUTABLE); 
            
tm64 = new_timestamp; //new_timestamp is properly calculated, no issue here

TAndroidHelper::AlarmManager->setExactAndAllowWhileIdle(TJAlarmManager::JavaClass->RTC_WAKEUP,tm64,PendingIntent);

清单文件权限与配置 #

<uses-permission android:name="android.permission.SCHEDULE_EXACT_ALARM" />
<uses-permission android:name="com.android.alarm.permission.SET_ALARM" />
...
<activity
  android:name="com.embarcadero.firemonkey.FMXNativeActivity"
  android:label="MyApp"
  android:exported="true"
  android:configChanges="orientation|keyboard|keyboardHidden|screenSize"
  android:launchMode="singleTask">
    <!-- Tell NativeActivity the name of our .so -->
    <meta-data android:name="android.app.lib_name" android:value="MyApp" />
    <intent-filter>
        <action android:name="android.intent.action.MAIN" />
        <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>
</activity>

疑问与求助 #

• 代码中Intent->setClassName(TAndroidHelper::Context, StringToJString("com.embarcadero.firemonkey.FMXNativeActivity"));的写法是否正确？
• 是否缺少必要的Intent标志位？
• 如何解决Android 13下闹钟触发后无法启动应用的问题？
