Play animated GIF using android.graphics.Movie, with Movie.decodeStream(InputStream)

This example implement a custom view, GifView, to display animated GIF using android.graphics.Movie, load movie with with Movie.decodeStream(InputStream).

Download and copy the GIF file (android_er.gif) to /res/drawable/ folder.

Create GifView.java extends View
package com.example.androidgif;

import java.io.InputStream;

import android.content.Context;
import android.graphics.Canvas;
import android.graphics.Movie;
import android.util.AttributeSet;
import android.view.View;

public class GifView extends View {
 
 private InputStream gifInputStream;
 private Movie gifMovie;
 private int movieWidth, movieHeight;
 private long movieDuration;
 private long mMovieStart;

 public GifView(Context context) {
  super(context);
  init(context);
 }

 public GifView(Context context, AttributeSet attrs) {
  super(context, attrs);
  init(context);
 }

 public GifView(Context context, AttributeSet attrs, 
   int defStyleAttr) {
  super(context, attrs, defStyleAttr);
  init(context);
 }
 
 private void init(Context context){
  setFocusable(true);
  gifInputStream = context.getResources()
    .openRawResource(R.drawable.android_er);
  
  gifMovie = Movie.decodeStream(gifInputStream);
  movieWidth = gifMovie.width();
  movieHeight = gifMovie.height();
  movieDuration = gifMovie.duration();
 }

 @Override
 protected void onMeasure(int widthMeasureSpec, 
   int heightMeasureSpec) {
  setMeasuredDimension(movieWidth, movieHeight);
 }
 
 public int getMovieWidth(){
  return movieWidth;
 }
 
 public int getMovieHeight(){
  return movieHeight;
 }
 
 public long getMovieDuration(){
  return movieDuration;
 }

 @Override
 protected void onDraw(Canvas canvas) {

  long now = android.os.SystemClock.uptimeMillis();
        if (mMovieStart == 0) {   // first time
            mMovieStart = now;
        }
        
        if (gifMovie != null) {

            int dur = gifMovie.duration();
            if (dur == 0) {
                dur = 1000;
            }

            int relTime = (int)((now - mMovieStart) % dur);
            
            gifMovie.setTime(relTime);

            gifMovie.draw(canvas, 0, 0);
            invalidate();
            
        }
        
 }

public class MainActivity extends Activity {

 TextView textViewInfo;
 GifView gifView;
 
 @Override
 protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.activity_main);
  gifView = (GifView)findViewById(R.id.gifview);
  textViewInfo = (TextView)findViewById(R.id.textinfo);

  String stringInfo = "";
  stringInfo += "Duration: " + gifView.getMovieDuration() + "\n";
  stringInfo += "W x H: " 
    + gifView.getMovieWidth() + " x " 
    + gifView.getMovieHeight() + "\n";
   
  textViewInfo.setText(stringInfo);

 }

}

IMPORTANT!
Modify AndroidManifest.xml to turn OFF hardwareAccelerated. Read remark on the bottom.
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.androidgif"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="19" />

    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name="com.example.androidgif.MainActivity"
            android:label="@string/app_name"
            android:hardwareAccelerated="false" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>

Thanks dude !

The final remark provides a direct solution to the problem I encountered. Thank you so much~

john watson said...

Hi..Thank you for post.but i want to pause or stop gifView.Can you please give me a solution for that?

Sashka Kucherov said...

gifInputStream = context.getResources()
.openRawResource(R.drawable.android_er);

even putting + does not help to solve this problem. an error

Bimal Parajuli said...

gifInputStream = context.getResources()
.openRawResource(R.drawable.some_gif);

# some_gif cannot be resolved, it throws an error : wrong kind of resource identifier

On an emulator you have to deactivate HW acceleration in your manifest or at least
deactivate it on your view : setLayerType(View.LAYER_TYPE_SOFTWARE, null);

I tested an animated gif with the movie object (not your code, but same result)
and concluded ( android 4.4 ):
- Bad image quality (no antialias, lookss horrible )
- frame delays are not respected (0ms delay between images)
- other users noticed late starts (time to load?)

on stackoverflow i found that someone created a gif decoder with a drawable object (to lazy, not enough time to do it myself)
and it works much better :
- no need to deactivate hw acceleration
- better image quality
- full control over the framerate (by setting the delay manually)

here's the link :

Somebody tried to run gif reverse(from end to start)? Performance is terrible. I don't know why but it seems like something with Movie class inner implementation.
