我正在尝试在我的离子应用程序上使用 API 级别 29，并且我要求应用程序询问用户“始终允许”位置。我已经添加了所有建议的修改。

我的 AndroidManifest.xml：

 <uses-permission android:name="android.permission.ACCESS_BACKGROUND_LOCATION">
 <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION">
 <uses-permission android:name="android.permission.ACTIVITY_RECOGNITION">
 <uses-permission android:name="android.permission.PERMISSION.FOREGROUND_SERVICE">

我的app.component.ts：

initializeApp() {
    this.platform.ready().then(() => {
      this.statusBar.styleDefault();
      this.splashScreen.hide();
      this.setProviders();
      this.checkBackgroundPermission();
    });
  }

private async checkBackgroundPermission() {
    try {
      const result = await this.androidPermissions.checkPermission(this.androidPermissions.PERMISSION.ACCESS_BACKGROUND_LOCATION);
      if (!result || result.hasPermission === false) {
        this.requestPermissions();
      }
    } catch (error) {
      this.requestPermissions();
    }
  }

 private async requestPermissions() {
    try {
      const data = await this.androidPermissions.requestPermissions([
        this.androidPermissions.PERMISSION.ACCESS_BACKGROUND_LOCATION,
        this.androidPermissions.PERMISSION.ACCESS_COARSE_LOCATION,
        this.androidPermissions.PERMISSION.ACCESS_FINE_LOCATION,
        this.androidPermissions.PERMISSION.ACTIVITY_RECOGNITION,
        this.androidPermissions.PERMISSION.FOREGROUND_SERVICE
      ]);
      if (!data.hasPermission) {
        throw new Error('No permission');
      }
    } catch …
