Android Question MP3 conversion error

[uniplan]

I have recorded an audio file in .wav format with AudioStreamer library.
I am able to correctly hear the .wav file produced.
I tried to convert the wav files to mp3 with liblameEncoder library.
I use this code:

Try
    Dim LameEncoder As liblameEncoder
    LameEncoder.Initialize("LameEncoder")
   
    If LameEncoder.SetFiles(File.Combine(perc_to_save, mFileName), File.Combine(perc_to_save, mFileNameMP3)) Then
        ProgressDialogShow2("Encoding...", False)
        LameEncoder.Encode
    Else
        Log("An error occurred while calling LameEncoder.SetFiles")
        CallSub2(module, eventName,"KO")
    End If
Catch
    Log(LastException)
End Try

But I have this error:

[Erel]

Are you testing it on a real device?
What is the value of targetSdkVersion (http://stackoverflow.com/questions/32346402/libavcodec-so-has-text-relocations) ?

 

[uniplan]

Yes. I have tested it on real device (Huawei P9 lite and Samsung S6).

This is my targetSdkversion:

<uses-sdk android:minSdkVersion="7" android:targetSdkVersion="24"/>

 

[Erel]

Try to set the targetSdkVersion to 22.

 

[uniplan]

What this implies for compatibility with later versions?

 

[Erel]

The targetSdkVersion value doesn't affect the compatibility or older or newer devices.

 

[uniplan]

I tried to set the targetSDKversion to 22 but when I compile I have this error:

[100%] /data/local/tmp/map_RAPID_DEBUG.apk
pkg: /data/local/tmp/map_RAPID_DEBUG.apk
Failure [INSTALL_FAILED_PERMISSION_MODEL_DOWNGRADE]

 

[Erel]

You will need to first uninstall the existing app from the device.

 

[uniplan]

I had just solved this way.
thanks.

 

[uniplan]

setting the targetSDKversion to 22 all work correctly.
Thanks.
