help me please
Its because you are calling stop on a null object. You should check the state of your MediaRecorder before stopping
According to the official example from google you need to do the following when stop recording.
// stop recording and release camera
mMediaRecorder.stop(); // stop the recording
releaseMediaRecorder(); // release the MediaRecorder object
And releaseMediaRecorder() is look like,
private void releaseMediaRecorder(){
if (mMediaRecorder != null) {
// clear recorder configuration
mMediaRecorder.reset();
// release the recorder object
mMediaRecorder.release();
mMediaRecorder = null;
}
}

I just started working on an audio recorder app. So far, the app can record audio and play it. My end goal is to be able to save multiple audio files to the device. How would I do this? Can I use SharedPreferences? I haven't been able to find anything.
public class MainActivity extends AppCompatActivity {
Button play;
Button stop;
Button record;
private MediaRecorder myAudioRecorder;
private String outputFile = null;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
play=(Button)findViewById(R.id.button3);
stop=(Button)findViewById(R.id.button2);
record=(Button)findViewById(R.id.button);
stop.setEnabled(false);
play.setEnabled(false);
FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
fab.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
try {
outputFile = Environment.getExternalStorageDirectory().getAbsolutePath() + "/recording.3gp";;
myAudioRecorder = new MediaRecorder();
myAudioRecorder.setAudioSource(MediaRecorder.AudioSource.MIC);
myAudioRecorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
myAudioRecorder.setAudioEncoder(MediaRecorder.OutputFormat.AMR_NB);
myAudioRecorder.setOutputFile(outputFile);
myAudioRecorder.prepare();
myAudioRecorder.start();
}
catch (IllegalStateException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
stop.setEnabled(true);
Toast.makeText(getApplicationContext(), "Recording started", Toast.LENGTH_LONG).show();
}
});
record.setOnClickListener(new View.OnClickListener() {

Create a folder in your external storage and store each file with a timestamp appended to the name of the file.
You can list all the video / audio files stored in this folder and select which video / audio you want to play anytime.
Get all files
public void displayAllFilesInFolder() {
List<String> filepath = new ArrayList<String>();
if (!hasSDCard()) {
return;
}
File dir = new File(android.os.Environment.getExternalStorageDirectory() + "folderName");
if (!dir.exists()) {
return;
}
File listAllFiles[] = dir.listFiles();
if (listAllFiles != null) {
for (int i = 0; i < listAllFiles.length; i++) {
if (!listAllFiles[i].isDirectory()) {
filepath.add(listAllFiles[i].getAbsolutePath());
}
}
}
}
Check if SD is mounted
private boolean hasSDCard(){
Boolean isSDPresent = android.os.Environment.getExternalStorageState().equals(android.os.Environment.MEDIA_MOUNTED);
if(isSDPresent) {
return true;
}
else{
return false;
}
}
You're already saving it to a file:
Environment.getExternalStorageDirectory().getAbsolutePath() + "/recording.3gp";
You just need to add more logic to pick a filename that doesn't already exist.
I am working on an App that requires recording a audio
Here's my partial code
private MediaRecorder myAudioRecorder;
private String outputFile = null;
private Button start, stop, play;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
start = (Button) findViewById(R.id.button1);
stop = (Button) findViewById(R.id.button2);
play = (Button) findViewById(R.id.button3);
stop.setEnabled(false);
play.setEnabled(false);
outputFile = Environment.getExternalStorageDirectory().getAbsolutePath() + "/myrecording.3gp";;
myAudioRecorder = new MediaRecorder();
myAudioRecorder.setAudioSource(MediaRecorder.AudioSource.MIC);
myAudioRecorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
myAudioRecorder.setAudioEncoder(MediaRecorder.OutputFormat.AMR_NB);
myAudioRecorder.setOutputFile(outputFile);
}
public void start(View view) throws IllegalArgumentException, SecurityException, IllegalStateException, IOException {
try {
myAudioRecorder.prepare();
myAudioRecorder.start();
} catch (IllegalStateException e) {
e.printStackTrace();
}catch (IOException e) {
e.printStackTrace();
}
start.setEnabled(false);
stop.setEnabled(true);
Toast.makeText(getApplicationContext(), "Recording Started", Toast.LENGTH_LONG).show();
}
The above code threw IllegalStateException. I have every permission entered in AndroidManifest.xml , I am very sure there's nothing wrong in AndroidManifest.xml.
I have read several solution but none of them working. How can I solve this problem?
public void stop(View view) {
myAudioRecorder.stop();
myAudioRecorder.release();
myAudioRecorder = null;
stop.setEnabled(false);
play.setEnabled(true);
Toast.makeText(getApplicationContext(), "Audio Recorded successfully", Toast.LENGTH_LONG).show();
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
public void play(View view) throws IllegalArgumentException, SecurityException, IllegalStateException, IOException {
MediaPlayer m = new MediaPlayer();
m.setDataSource(outputFile);
m.prepare();
m.start();
Toast.makeText(getApplicationContext(), "Audio Playing", Toast.LENGTH_LONG).show();
}
}
I have developed this small MediaRecorder application. I have 3 buttons- Play (for Start Recording), Pause (for stop recording), Max (for finding Max Amplitude). I Googled to get it correct, but nothing worked fine for me.
The problem is it always give me 0 for getMaxAmplitude.
Below is the code i am using. Can any one please help
public class MainActivity extends Activity {
Button play,pause, max;
String outputFile = Environment.getExternalStorageDirectory().
getAbsolutePath() + "/myexampl.3gp";
MediaRecorder mrecorder=new MediaRecorder();
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
play = (Button)findViewById(R.id.button1);
pause= (Button)findViewById(R.id.button2);
max = (Button)findViewById(R.id.button3);
mrecorder = new MediaRecorder();
mrecorder.setAudioSource(MediaRecorder.AudioSource.MIC);
mrecorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
mrecorder.setAudioEncoder(MediaRecorder.OutputFormat.AMR_NB);
mrecorder.setOutputFile(outputFile);
play.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
try {
mrecorder.prepare();
} catch (IllegalStateException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
mrecorder.start();
Toast.makeText(getApplicationContext(), "Starts Recording!",
Toast.LENGTH_SHORT).show();
}
});
pause.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
try {
mrecorder.stop();
} catch (IllegalStateException e) {
e.printStackTrace();
}
mrecorder.release();
Toast.makeText(getApplicationContext(), "Stops Recording!",
Toast.LENGTH_SHORT).show();
}
});
max.setOnClickListener(new OnClickListener() {
int ampl=0;
#Override
public void onClick(View v) {
try {
ampl=mrecorder.getMaxAmplitude();
} catch (IllegalStateException e) {
e.printStackTrace();
}
Toast.makeText(getApplicationContext(), String.valueOf(ampl),
Toast.LENGTH_SHORT).show();
}
});

is there anyway I can send an email when I press the save button with OUTPUT_FILE path from sdcard. (I didn't implement the save button yet)
Should I change String to Uri instead to send an email?
I don't know how I should implement the save button making it to send an email with the audio file attached. Any suggestions? Thanks in advance!

}
In your activity,you can register a phone state listener by calling public void listen (PhoneStateListener listener, int events) in the TelephonyManager class. See here. Also,You can call Context.getSystemService(Context.TELEPHONY_SERVICE) to get an instance of the TelephonyManager object.
