Calling MediaRecorder crashes app in AndroidStudio

I am trying to create a class that sets and starts audio recording but as soon as I click the button the app crashes. Iv isolated the problem to where I set the parameters for the MediRecorder.
private void startRec() throws IOException {
if (mrecorder!=null)
mrecorder.release();
mrecorder= new MediaRecorder();
-> mrecorder.setAudioSource(MediaRecorder.AudioSource.MIC);
/*
mrecorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
mrecorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
mrecorder.setOutputFile(MFILE);
mrecorder.prepare();
mrecorder.start();
*/
}
It crashes when the line with the arrow above the start of the notes is executed. I added the following permission to the manifest as well:
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.RECORD_AUDIO" />
Any help much appreciated.

The code that leads to error
public void CopyReadAssets(String url) {
AssetManager assetManager = getAssets();
InputStream in = null;
OutputStream out = null;
File file = new File(getFilesDir(), url);
try {
in = assetManager.open(url);
out = openFileOutput(file.getName(),
Context.MODE_WORLD_READABLE);
copyFile(in, out);
in.close();
in = null;
out.flush();
out.close();
out = null;
}
catch (Exception e) {
Log.e("tag", e.getMessage());
}
String path = "file://" + getFilesDir() + "/"+url;
openPdfIntent(path);
}
private void openPdfIntent(String path) {
// TODO Auto-generated method stub
try {
final Intent intent = new Intent(Question_Point_Main.this, Pdf.class);
intent.putExtra(PdfViewerActivity.EXTRA_PDFFILENAME, path);
startActivity(intent);
} catch (Exception e) {
e.printStackTrace();
}
}

Try these steps:
Step 1: Create a folder "lib", and copy all third-party jars here;
Step 2: Add these jars to build path;
Step 3: Use the folder as Source Folder(shown below).

Maybe you just forgot the underscore and you meant com.question_point.pdf.Pdf?
It would be easier to tell if you could post the relevant code where you make the call that leads to the Exception.

Note Your code to Capture Map Screen is Correct and if still you have confusion than
Please Make sure Each Step Below:-
Below are the steps to capture screen shot of Google Map V2 with example
Step 1. open Android Sdk Manager (Window > Android Sdk Manager) then Expand Extras now update/install Google Play Services to Revision 10 ignore this step if already installed
Read Notes here https://developers.google.com/maps/documentation/android/releases#august_2013
Step 2. Restart Eclipse
Step 3. import com.google.android.gms.maps.GoogleMap.SnapshotReadyCallback;
Step 4. Make Method to Capture/Store Screen/image of Map like below
public void CaptureMapScreen()
{
SnapshotReadyCallback callback = new SnapshotReadyCallback() {
Bitmap bitmap;
#Override
public void onSnapshotReady(Bitmap snapshot) {
// TODO Auto-generated method stub
bitmap = snapshot;
try {
FileOutputStream out = new FileOutputStream("/mnt/sdcard/"
+ "MyMapScreen" + System.currentTimeMillis()
+ ".png");
// above "/mnt ..... png" => is a storage path (where image will be stored) + name of image you can customize as per your Requirement
bitmap.compress(Bitmap.CompressFormat.PNG, 90, out);
} catch (Exception e) {
e.printStackTrace();
}
}
};
myMap.snapshot(callback);
// myMap is object of GoogleMap +> GoogleMap myMap;
// which is initialized in onCreate() =>
// myMap = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map_pass_home_call)).getMap();
}
Step 5. Now call this CaptureMapScreen() method where you want to capture the image
in my case i am calling this method on Button click in my onCreate() which is working fine
like:
Button btnCap = (Button) findViewById(R.id.btnTakeScreenshot);
btnCap.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
try {
CaptureMapScreen();
} catch (Exception e) {
// TODO: handle exception
e.printStackTrace();
}
}
});

//add up the size so we know how much is downloaded
downloadedSize += bufferLength;
int progress=(int)(downloadedSize*100/totalSize);
//this is where you would do something to report the prgress, like this maybe
//updateProgress(downloadedSize, totalSize);
}
//close the output stream when done
fileOutput.close();
} catch (MalformedURLException e1) {

} catch (FileNotFoundException e1) {

} catch (IOException e1) {
// TODO Auto-generated catch block

}
this code keeps coming out with the FileNotFoundException, but the file is there, if you follow the url you can see it.
does it have to be hosted in a specific way? or is it something wrong with the way im getting it

FileInputStream in Another class?

I'm loading a file that has been saved by another class via the FileOutputstream method. Anyway, I want to load that file in another class, but it either gives me syntax errors or crashes my App.
The only tutorials I could find where they saved and loaded the file in the same class, but I want to load it up in another class and couldn't find how to solve the problem of loading into another class.
Thanks

The FILENAME string in the ChatService class is null. So you get a NullPointerException when you try to load a file using fis = openFileInput(FILENAME).
Also, your read loop throws away the data:
while (fis.read(dataArray) != -1)
;
It needs to collect the data and set the value of your collected String.

The stack trace tells you everything you need to know.
The error is a NullPointerException (meaning that you pass a null reference to a method expecting a non null reference, or that you call a method on a null reference).
The error occurs inside some android code (ContextWrapper.openFileInput()), which is called by your ChatService.onCreate() method, on line 25.
The line 25 is the following line:
fis = openFileInput(FILENAME);
So the error is clear: FILENAME is null. You haven't initialized it before this method is called.

I'm not sure about your program flow and if your two classes are running in the same thread, but it looks like you have a program flow issue. You are trying to open the file and getting a NullPointerException. Make sure the file is created and you have the correct reference to it before attempting to read.
If they are running in separate threads then you might try something like this:
try {
int waitTries=1;
fis = openFileInput(FILENAME);
while(fis.available()<EXPECTEDSIZE && waitTries++<10)
Tread.sleep(50);
}
If you know how large the file should be (EXPECTEDSIZE is some constant you will set), then this may be what you are looking for.
