Android Trick - Pick photo from Gallery and 3rd party app

-
In Android we can using Intent to share data between applications.

 Simple usage for this part is Picking images or photos from the other applications.

 Normally the codes is like the following:
private void pickPhotoFromGallery() {
    Intent intent = new Intent();
    intent.setType("image/*");
    intent.setAction(Intent.ACTION_PICK);

    //following line code will specify the dialog title of choosing different content source app
    startActivityForResult(Intent.createChooser(intent, "Complete action using"),SELECT_PHOTO);
}

Noticed that if I set Intent Action as Intent.ACTION_PICK it will only select images from System Gallery App.

if I called 
intent.setAction(Intent.ACTION_GET_CONTENT); 
It will get from the other apps.

And the result is not same. From Gallery app the uri format is like :
content://xxx/xx/xx
but the other app will return uri like :
file:///xxx/xx/xx

Actually the Gallery app returned is not the absolute path of that image but the others app return file absolute path.

So create this kind of function to get the absolute path:

public static String getPath(Context context, Uri uri) {
    String path = uri.toString();
    if(path.startsWith("file:")){
        return path.substring(7);
    }
    String[] projection = { MediaStore.Images.Media.DATA };
    Cursor cursor = context.getContentResolver().query(uri, projection,null, null, null);
    if (cursor == null)
        return null;
    int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
    cursor.moveToFirst();
    String s = cursor.getString(column_index);
    cursor.close();
    return s;
}


Following all the codes about this part:

protected static final int SELECT_PHOTO = 100;
protected static final int CROP_PHOTO = 101;
protected static final int CAPTURE_PHOTO = 102;


private void pickPhotoFromCamera() {
try {
    Intent captureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
    startActivityForResult(captureIntent, CAPTURE_PHOTO);
} catch (ActivityNotFoundException anfe) {
    // display an error message
    String errorMessage = "Whoops - your device doesn't support capturing images!";
    Utils.Toast(ActivityBase.this, errorMessage);
}
}

private void pickPhotoFromGallery() {
    Intent intent = new Intent();
    intent.setType("image/*");
    intent.setAction(Intent.ACTION_GET_CONTENT);
    // intent.setAction(Intent.ACTION_PICK);

    startActivityForResult(
    Intent.createChooser(intent, "Complete action using"),SELECT_PHOTO);
}

private void cropPhotoFromUri(Uri uri) {
    if(uri == null){
        return ;
    }
    MyLog.i(TAG, "select img uri:"+uri.toString());
    try {
        Intent intent = new Intent("com.android.camera.action.CROP");
        intent.setData(uri);
        intent.putExtra("crop", "true");
        intent.putExtra("outputX", 256);
        intent.putExtra("outputY", 256);
        if (flagSqure) {
        intent.putExtra("aspectX", 1);
        intent.putExtra("aspectY", 1);
    }
    intent.putExtra("scale", true);
    intent.putExtra("return-data", true);
    // intent.putExtra("noFaceDetection", true);
    // intent.putExtra("output", Uri.fromFile(someOutputFile));
    startActivityForResult(intent, CROP_PHOTO);
    } catch (ActivityNotFoundException anfe) {
        // display an error message
        String errorMessage = "Whoops - your device doesn't support the crop this image! upload directly";
        Utils.Toast(ActivityBase.this, errorMessage);
        File file = new File(Utils.getPath(ActivityBase.this, uri));
        if (photoListener != null) {
            photoListener.onPhotoSelected(file);
        }
    }
}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent imageReturnedIntent) {

switch (requestCode) {
case SELECT_PHOTO:
    if (resultCode == RESULT_OK) {
        Uri selectedImage = imageReturnedIntent.getData();
        cropPhotoFromUri(selectedImage);
    }
    break;
case CAPTURE_PHOTO:
if (resultCode == RESULT_OK) {
    Uri selectedImage = imageReturnedIntent.getData();
    MyLog.i(TAG, "get img url:" + selectedImage.getPath());
    cropPhotoFromUri(selectedImage);
}
break;
case CROP_PHOTO:
    if (resultCode == RESULT_OK) {
        MyLog.i(TAG, "" + imageReturnedIntent.getData());
        Bundle extras = imageReturnedIntent.getExtras();
        Bitmap bmp = extras.getParcelable("data");
        ByteArrayOutputStream bos = new ByteArrayOutputStream();
        bmp.compress(CompressFormat.JPEG, 75, bos);
        byte[] data = bos.toByteArray();
        if (photoListener != null) {
            photoListener.onPhotoSelected(data);
        }
    }
    break;
}
super.onActivityResult(requestCode, resultCode, imageReturnedIntent);
}

A wired issue of MediaPlayer on Android

-
Background Our application needs to play mp3 files served by our server. What we used to do is just using MediaPlayer to play that URL. However, there are more and more customers complaint about Music playing being cut off quite frequently. So I had to dig into legacy codes to find out the reason. Reproduce From existing codebase, I could tell our app respects MediaPlayer's   OnErrorListener   and if MediaPlay throw out any Error, app will try to catch them and recover. Unfortunately, we did not receive any exceptions for this part according to our Fabric crashlytics report. Besides that, this bug is not really easy to reproduce.   I knew it must be caused by user's network issue. So I tried Charles proxy and using its throttling feature. However it seems like MediaPlayer would have a special connection after connecting and Charles' throttling can not control that connection. Then I also tried Android Emulator's build-in network status simulation feature. Sti

Problem when using Jackson json parser in Android.

-
I really like to use Jackson library to parse json string. Just now met a problem org.codehaus.jackson.JsonParseException: Illegal unquoted character ((CTRL-CHAR, code 10)): has to be escaped using backslash to be included in string value The reason is my string contains some newline symbols. Then actually the string is not "valid" or "formatted" Json .  Finally I found one quick solution . try { JSONObject b = new JSONObject ( decodedPayload ); decodedPayload = b . toString (); } catch ( JSONException e ) { e . printStackTrace (); } That JSONObject can formatted that unformatted json string . Might be there are some other better solution.

Gradle issue - peer not authenticated

-
When we tried to migrate our Gitlab from Http to Https , we met a problem of Maven Central which was also maintained as a Git repo. peer not authenticated Basically the reason is JVM can not pick up trusted CA from local machine. So we manually trusted it with commands. 1. Get the certificate file (.cer). I am using Mac so I just trusted that certificate through browser and it will be saved in Keychain Access. Then I just export that certificate as .cer file. 2. Copy the .cer file to $JDK_HOME/jre/lib/security folder 3. Run the command keytool - import - alias <alias_of_this_cert> - file < cert_file_name_you_exported . cer > - keystore cacerts - storepass changeit 4. Gradle is able to find dependencies now. NOTE : how to get current JAVA_HOME: /usr/libexec/java_home [-v '1.8'] how to transfer file through ssh: cat {origin file} | ssh {username}@{remote host} "cat - > {target file}"
