Android Question [Things] PeripheralManager Error - java.lang.RuntimeException: Stub!

[Adie]

Ok, I upgraded to the latest Android Things and now also get the error.

Background:
1. SDK 25
2. All modules up to date.
3. Original app worked 100% on older Things and B4A 7.
4. B4A 8

The code supplied is just two tests:
1. Define pm
2. Init pm - where the app crash
3. I removed the line:

    File.WriteString(File.DirRootExternal, "Limits.txt", "100~200" )

because I could not get write access to external

What I noted:
1. If I remember correctly I HAD to put this line

  AddApplicationText(<uses-library android:name="com.google.android.things"/>)

in the manifest editor or the app will not execute on the Pi.
Now it does not matter.

2. I was under the impression the marked line in the 'AndroidManifest.xml' will allow write access to the external storage. does not seems to do anything.

3. adding

 <uses-permission android:name="com.google.android.things.permission.USE_PERIPHERAL_IO" />

as per Google to the manifest does nothing.

Sample of final manifest.

<?xml version="1.0" encoding="utf-8"?>
<manifest
    xmlns:android="http://schemas.android.com/apk/res/android"
    package="b4a.example"
    android:versionCode="1"

    <uses-permission android:name="android.permission.BLUETOOTH_ADMIN"/>
    <application
        android:icon="@drawable/icon"
        android:label="B4A Example">
      
        <uses-library android:name="com.google.android.things"/>
        <activity
            android:windowSoftInputMode="stateHidden"
            android:launchMode="singleTop"
            android:name=".main"
            android:label="B4A Example"
            android:screenOrientation="unspecified">
            <intent-filter>
               <action android:name="android.intent.action.MAIN" />
               <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
          
        </activity>
        <service android:name=".starter">
        </service>
        <receiver android:name=".starter$starter_BR">
        </receiver>
    </application>
</manifest>

Any help will be appreciated.

The B4A version is not relevant.

Leave the permission issue for now. Use File.DirInternal instead.

Can you post the full error message from the logs?

THANK YOU!!!! all working again.

The system is used in a foundry to remotely monitor the mass in the ladle. (Radio modems) The last few days was a nightmare for them as they had to estimate the mass and the mold was not filled correctly a few times.

The power supply of the Pi packed up and damaged the SD card.

thanks again.
