问题
I have a button, which opens up a dialog box asking user to either "Take Picture" or "Choose from gallery".
I am facing issues when user "Take photo" , image is getting clicked, and for verification purpose I am setting Bitmap image inside the circularImage view, but when I go to specified location path of the image, either Image is not there or Image is corrupted.
Also I am trying to upload the image to the server using AsyncHttpClient in android but not being able to do it successfully.
Everytime I am getting Java Socket TimeOut Exception.
Below is the code for my Camera Intent Activity
public class AddAnUpdateActivity extends ActionBarActivity {
@Override
protected void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
this.composeEditText = (EditText) findViewById(R.id.composeEditText);
setContentView(R.layout.add_update);
ProfilePictureImage = (CircularImageView) findViewById(R.id.ProfilePic);
insertVideo = (ImageButton) findViewById(R.id.insertVideoButton);
setBtnListenerOrDisable(insertVideo,mTakeVidOnClickListener, MediaStore.ACTION_VIDEO_CAPTURE);
insertImage = (ImageButton) findViewById(R.id.insertImageButton);
insertImage.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
selectImage();
}
});
}
private void setBtnListenerOrDisable(ImageButton btn,
Button.OnClickListener onClickListener,
String intentName) {
if (isIntentAvailable(this, intentName)) {
btn.setOnClickListener(onClickListener);
} else {
btn.setClickable(false);
}
}
private boolean isIntentAvailable(Context context, String action) {
final PackageManager packageManager = context.getPackageManager();
final Intent intent = new Intent(action);
List<ResolveInfo> list =
packageManager.queryIntentActivities(intent,
PackageManager.MATCH_DEFAULT_ONLY);
return list.size() > 0;
}
private void selectImage() {
final CharSequence[] options = { "Take Photo", "Choose from Gallery","Cancel" };
AlertDialog.Builder builder = new AlertDialog.Builder(AddAnUpdateActivity.this);
builder.setTitle("Add Photo!");
builder.setItems(options,new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int item) {
if(options[item].equals("Take Photo"))
{
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
File f = new File(android.os.Environment.getExternalStorageDirectory(), "Image.jpg");

{

I simplified your code .keep reference of file path global
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
File f = new File(android.os.Environment.getExternalStorageDirectory(), "Image.jpg");
globalpath =f.getAbsolutePath(); //String make it global
intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(f));
startActivityForResult(intent, 1);
//your onactivityresult
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == RESULT_OK) {
if (requestCode == 1) {
File myfile = new File(globalpath);
Bitmap bitmap;
BitmapFactory.Options bitmapOptions = new BitmapFactory.Options();
bitmap = BitmapFactory.decodeFile(myfile.getAbsolutePath(),
bitmapOptions);
ProfilePictureImage.setImageBitmap(bitmap);
String path = android.os.Environment
.getExternalStorageDirectory()
+ File.separator
+ "Pictures" + File.separator + "Screenshots";
OutputStream outFile;
File file = new File(path, String.valueOf(System
.currentTimeMillis()) + ".jpg");
try {
outFile = new FileOutputStream(file);
bitmap.compress(Bitmap.CompressFormat.JPEG, 85, outFile);
outFile.flush();
outFile.close();
myfile.delete();
} catch (Exception e) {
e.printStackTrace();
}
}
}
}

Depending on your Android version and device, the camera intent is to be implemented differently. Check out https://github.com/ralfgehrer/AndroidCameraUtil. The code is tested on 100+ devices.

After take the photo remember to use this:
sendBroadcast(new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE, Uri.fromFile(myNewFile)));
to scan the media file in your gallery. If you doesn't do it your photo will appear after some time. You can do it in onClick:
insertImage.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
selectImage();
sendBroadcast(new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE, Uri.fromFile(myNewFile)));
}
});
