I want to share a mp3 file to whatsapp. I found this question on Stack Overflow, but the accepted answer does not work for me. If I try to share it with whatsapp it says "Sharing failed, please try again":
File dest = Environment.getExternalStorageDirectory();
InputStream in = getResources().openRawResource(R.raw.sound);
try
{
OutputStream out = new FileOutputStream(new File(dest, "sound.mp3"));
byte[] buf = new byte[1024];
int len;
while ( (len = in.read(buf, 0, buf.length)) != -1)
{
out.write(buf, 0, len);
}
in.close();
out.close();
}
catch (Exception e) {
e.printStackTrace();}
Intent share = new Intent(Intent.ACTION_SEND);
share.putExtra(Intent.EXTRA_STREAM, Uri.parse(Environment.getExternalStorageDirectory().toString() + "/sound.mp3"));
share.setType("audio/mp3");
startActivity(Intent.createChooser(share, "Shared"));
Here is the full MainActivity.java:
package com.example.aaron.sharetest;

import android.content.pm.PackageManager;

public class MainActivity extends AppCompatActivity {
Button shareBtn;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final File FILES_PATH = new File(Environment.getExternalStorageDirectory(), "Android/data/com.example.aaron.sharetest/files");
File sharefile= new File(FILES_PATH, "sound.mp3") ;
putExtra(Intent.EXTRA_STREAM, Uri.fromFile(sharefile));
shareBtn = (Button)findViewById(R.id.shareBtn);
ActivityCompat.requestPermissions(MainActivity.this,
new String[]{Manifest.permission.READ_EXTERNAL_STORAGE},
1);
shareBtn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
if (Environment.MEDIA_MOUNTED.equals(
Environment.getExternalStorageState())) {
if (!FILES_PATH.mkdirs()) {
Log.w("error", "Could not create " + FILES_PATH);
}
} else {
Toast.makeText(MainActivity.this, "error", Toast.LENGTH_LONG).show();
finish();
}
File dest = Environment.getExternalStorageDirectory();
InputStream in = getResources().openRawResource(R.raw.bibikurz);
try
{
OutputStream out = new FileOutputStream(new File(dest, "sound.mp3"));
byte[] buf = new byte[1024];
int len;
while ( (len = in.read(buf, 0, buf.length)) != -1)
{
out.write(buf, 0, len);
}
in.close();
out.close();
}
catch (Exception e) {
e.printStackTrace();
}
Intent share = new Intent(Intent.ACTION_SEND);
share.putExtra(Intent.EXTRA_STREAM, Uri.parse(Environment.getExternalStorageDirectory().toString() + "/sound.mp3"));
share.setType("audio/mp3");
startActivity(Intent.createChooser(share, "Shared"));
}
});
}
}
Of course I wrote this line in my Manifest:
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
What do I have to do to share the mp3 file to whatsapp, etc?
I tried so many accepted answers, but no one of them worked for me.
This is what I get in my LogCat:
