I'm trying to play audio from storage when i click on item, for some reason file returns false for exists(), i have read and write external storage permission, and file is there and doesn't seem damaged, my file is in .mp4 format, which i will play as audio type.

this is my permissions:

<uses-permission android:name="android.permission.INTERNET"/>

<uses-permission android:name="android.permission.READ_PHONE_STATE" />

<uses-permission android:name="android.permission.RECORD_AUDIO"/>

<uses-permission android:name="android.permission.READ_CONTACTS"/>

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>

provider:

<provider

        android:authorities="com.aliaskarurakov.android.mycallrecorderdemo"

        android:name="android.support.v4.content.FileProvider"

        android:exported="false"

        android:grantUriPermissions="true">

        <meta-data

        android:name="android.support.FILE_PROVIDER_PATHS"

        android:resource="@xml/provider_paths"/>

</provider>

xml:

<?xml version="1.0" encoding="utf-8"?>

<paths xmlns:android="http://schemas.android.com/apk/res/android">

    <external-path name="external_files" path="."/>

</paths>

this is my method:

    public void playAudio(){

        String path = Environment.getExternalStorageDirectory() + "/tempAudioFile/temp.mp4";

        Log.d("path", "onClick: path = "+path);

        Intent intent = new Intent(Intent.ACTION_VIEW);

        File file = new File(path);

        Log.i("", "onResponse: name "+file.getName());

        if (file.exists()){

            Log.i("", "onResponse: I EXIST");

        } else {

            Log.i("", "onResponse: dont exist?");

        }

        intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);

        intent.setDataAndType(getUriForFile(context,"com.aliaskarurakov.android.mycallrecorderdemo",file), "audio/*");

        context.startActivity(intent);

    }

You still need to ask for the permission at runtime. Call this function where needed.

private void checkReadStoragePermission(){

    if (ContextCompat.checkSelfPermission(getApplicationContext(), Manifest.permission.READ_EXTERNAL_STORAGE)

            != PackageManager.PERMISSION_GRANTED){

        ActivityCompat.requestPermissions(this,

                new String{Manifest.permission.READ_EXTERNAL_STORAGE},

                PERMISSION_REQUEST_READ_EXTENAL_STORAGE);

    }else{

        // Do your stuff here if permission is already granted by user

    }

}

And then handle if the user grants it or not.

@Override

public void onRequestPermissionsResult(int requestCode, @NonNull String permissions, @NonNull int grantResults) {

    switch (requestCode){

        // Here is the permission that you want

        case PERMISSION_REQUEST_READ_EXTENAL_STORAGE:

            if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED)

                // Do your stuff here if permission is granted by user



    }

    super.onRequestPermissionsResult(requestCode, permissions, grantResults);

}
