You can try AudioServiceFragmentActivity instead of AudioServiceActivity. More information about the different ways to define an audio service activity can be found in the audio_service documentation.

Onesignal errors in flutter: requires a placeholder substitution but no value for

Getting the following error when building APK (Flutter).
I added my Onesignal App ID even thou I'm not currently making use of it.
Someone mentioned that my Onesignal SDK is not properly installed: https://documentation.onesignal.com/docs/flutter-sdk-setup
but I don't think that's it.

This might help...
Try going to your
android/app/build.gradle
Find defaultConfig and add the following piece of code:
manifestPlaceholders = [
onesignal_app_id: 'ONE SIGNAL APP ID',
// Project number pulled from dashboard, local value is ignored.
onesignal_google_project_number: 'REMOTE'
]
defaultConfig {
// TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
applicationId "com.app.android"
...
manifestPlaceholders = [
onesignal_app_id: 'ONE SIGNAL APP ID HERE',
// Project number pulled from dashboard, local value is ignored.
onesignal_google_project_number: 'REMOTE'
]
}
Your Onesignal Google project number is your Firebase Sender ID.

You can use something like below
android {
defaultConfig {
manifestPlaceholders = [hostName:"www.example.com"]
}
...
}
You can then insert one of the placeholders into the manifest file as an attribute value like this:
<intent-filter ... >
<data android:scheme="https" android:host="${hostName}" ... />
...
</intent-filter>

Cause of Error Message "Error:(27) Tag <manifest> attribute package has invalid type 4."

When trying to build my app, I get the following error message: "Error:(27) Tag <manifest> attribute package has invalid type 4." Any ideas on what is causing this? Here is a copy of my manifest:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.dummy.tanc">
<application
android:supportsRtl="true"
android:allowBackup="true"
android:fullBackupContent="false"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<meta-data android:name="com.google.android.gms.games.APP_ID"
android:value="#string/app_id" />
<meta-data android:name="com.google.android.gms.version"
android:value="#integer/google_play_services_version"/>
<activity
android:name="com.google.example.games.tanc.MainActivity"
android:label="#string/title_activity_main"
android:screenOrientation="portrait" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>

I think it is because, in your manifest, you've set your package name (line 2) to be
package="com.dummy.tanc"
and in when defining the activity (line 18), you've used
android:name="com.google.example.games.tanc.MainActivity"
Because of this mismatch, the issue could be arising. Change the line 18 to
android:name="com.dummy.tanc.MainActivity"

It means attribute package has type float but not string.
I guess your package name contains only numbers, something like package="1.0".

AdMob still not working

I got a problem regarding Google AdMob:
I try to display a Interstitial, for this I have added the AdActivity, permissions and meta-tags to manifest.

In MainActivity:
mInterstitialAd = new InterstitialAd(this);
mInterstitialAd.setAdUnitId("xxx/xxx");
AdRequest adRequest = new AdRequest.Builder().build();
mInterstitialAd.loadAd(adRequest);
if (mInterstitialAd != null && mInterstitialAd.isLoaded()) {
mInterstitialAd.show();
}

Besides there is also a compilation error:
Conversion of dalvik format failed with error code 1
I tried about 20 answers, still not working.
I also dont know whether the problem is the unit id, I can change
mInterstitialAd.setAdUnitId("xxx/xxx");
to:
mInterstitialAd.setAdUnitId("xxx");
and I got the same errors.
I use the following external libraries:
android support v4&v7, picasso, ftpclient(commons, httpmime),FAB
Does somebody have a advice?
Greetings

Solution found!
Seems like some features in CyanogenMod blocks AdMob.
Flashed a new version WITHOUT Adaware and blocking Tools.
WORKING NOW :D

Thanks in advance.

Well, your error message says:
AndroidManifest.xml should include meta-data node with android:name="com.flurry.gms.ads.MY_AD_UNIT_ID" and not empty value for android:value
So I would start by adding that.
