I already chose images from gallery however, after that what should I do, I can't understand. Which library should be used? And how to implement it?
In my code below, How to get a ArrayList<File>images from gallery selection. I've used Jcodec Library. If any other solution is there then please suggest.
MainActivity.java:
public class MainActivity extends Activity {
GridView gridGallery;
Handler handler;
GalleryAdapter adapter;
Button btnGalleryPick;
Button btnGalleryPickMul;
ViewSwitcher viewSwitcher;
ImageLoader imageLoader;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
initImageLoader();
init();
}
private void initImageLoader() {
DisplayImageOptions defaultOptions = new DisplayImageOptions.Builder()
.cacheOnDisc().imageScaleType(ImageScaleType.EXACTLY_STRETCHED)
.bitmapConfig(Bitmap.Config.RGB_565).build();
ImageLoaderConfiguration.Builder builder = new ImageLoaderConfiguration.Builder(
this).defaultDisplayImageOptions(defaultOptions).memoryCache(
new WeakMemoryCache());
ImageLoaderConfiguration config = builder.build();
imageLoader = ImageLoader.getInstance();
imageLoader.init(config);
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == 200 && resultCode == Activity.RESULT_OK) {
String[] all_path = data.getStringArrayExtra("all_path");
ArrayList<CustomGallery> dataT = new ArrayList<CustomGallery>();
for (String string : all_path) {
CustomGallery item = new CustomGallery();
item.sdcardPath = string;
dataT.add(item);
}
viewSwitcher.setDisplayedChild(0);
adapter.addAll(dataT);
}
}
private void init() {
handler = new Handler();
gridGallery = (GridView) findViewById(R.id.gridGallery);
gridGallery.setFastScrollEnabled(true);
adapter = new GalleryAdapter(getApplicationContext(), imageLoader);
adapter.setMultiplePick(false);
gridGallery.setAdapter(adapter);
viewSwitcher = (ViewSwitcher) findViewById(R.id.viewSwitcher);
viewSwitcher.setDisplayedChild(1);
btnGalleryPick = (Button) findViewById(R.id.btnGalleryPick);
btnGalleryPick.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
if (gridGallery.getChildCount() == 0) {
Toast.makeText(getApplicationContext(), "Please Select Photo First", Toast.LENGTH_SHORT).show();
} else {
String location = String.valueOf(Environment.getExternalStorageDirectory());
File root = new File(Environment.getExternalStorageDirectory()
.getAbsolutePath() + "/Birthday/");
ArrayList<File> fileList = new ArrayList<File>();
File listFile[] = root.listFiles();
if (listFile != null && listFile.length > 0) {
for (int i = 0; i < listFile.length; i++) {
/*if (listFile[i].isDirectory()) {
fileList.add(listFile[i]);
getfile(listFile[i]);
} else {*/
if (listFile[i].getName().endsWith(".png")
|| listFile[i].getName().endsWith(".jpg")
|| listFile[i].getName().endsWith(".jpeg")
|| listFile[i].getName().endsWith(".gif"))
{
fileList.add(listFile[i]);
}
}
}
softwareMakeVideo(fileList, location, "test");
}
}
});
btnGalleryPickMul = (Button) findViewById(R.id.btnGalleryPickMul);
btnGalleryPickMul.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent i = new Intent(Action.ACTION_MULTIPLE_PICK);
startActivityForResult(i, 200);
}
});
}
public String softwareMakeVideo(ArrayList<File> images, String location,
String name) {
File directory = new File(location);
if (!directory.exists()) {
directory.mkdir();
}
File file = new File(directory, name + ".mp4");
try {

}
Bitmap frame = BitmapFactory.decodeFile(image.getAbsolutePath());
try {
encoder.encodeNativeFrame(this.fromBitmap(frame));
} catch (Exception e) {
e.printStackTrace();
}
}
encoder.finish();
} catch (IOException e) {
e.printStackTrace();
}
return file.getAbsolutePath();
}
public Picture fromBitmap(Bitmap src) {
Picture dst = Picture.create(src.getWidth(), src.getHeight(), ColorSpace.RGB);
fromBitmap(src, dst);
return dst;
}
private void fromBitmap(Bitmap src, Picture dst) {
int[] dstData = dst.getPlaneData(0);
int[] packed = new int[src.getWidth() * src.getHeight()];
src.getPixels(packed, 0, src.getWidth(), 0, 0, src.getWidth(), src.getHeight());
for (int i = 0, srcOff = 0, dstOff = 0; i < src.getHeight(); i++) {
for (int j = 0; j < src.getWidth(); j++, srcOff++, dstOff += 3) {
int rgb = packed[srcOff];
dstData[dstOff] = (rgb >> 16) & 0xff;
