Set GIF image to Custom ImageView

I have custom ImageView for animated GIF image. i want to show GIF image, I tried but in this case it is contain url in Async instead I want to show GIF image from raw folder without using Glide. Anyone have any idea how to show image? Please guyz help to solve this problem!!!
I tried this for set raw file
new GifStaticData() {
#Override

super.onPostExecute(drawable);
gifImageView.setImageResource(R.raw.earth_tilt_animation);

I had to play and pause the Gif image Glide - Cannot stop gif onClick- Getting TransitionDrawable instead of Animate/GifDrawable
The idea is to get drawable from view,checking if it is an instance of Gifdrawable and playing and pausing it.(Hoping the gif image is already playing)
Add this In OnClick of GifImageView
Drawable drawable = ((ImageView) v).getDrawable();
if (drawable instanceof GifDrawable) {
GifDrawable animatable = (GifDrawable) drawable;
if (animatable.isRunning()) {
animatable.stop();
} else {
animatable.start();
}
}

I found the solution of above problem using GifMovieView!!!
GifMovieViewer.java
public class GifMovieViewer extends Activity {
private Button btnStart;
private GifMovieView gif1;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.gif_movie_viewer);
gif1 = (GifMovieView) findViewById(R.id.gif1);
btnStart = (Button) findViewById(R.id.btnStart);
btnStart.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
gif1.setMovieResource(R.drawable.earth_tilt_animation);
//for pause
// gif1.setPaused(gif1.isPaused());
}
});
}
public void onGifClick(View v) {
GifMovieView gif = (GifMovieView) v;
gif.setPaused(!gif.isPaused());
}
}

Unable to implement custom touch listener on google map support fragment android

I am trying to handle events apart from the onCamerachange Listener such as knowing the event when the camera is dragged and released. For that I have taken help of a custom touch fragment and touch wrapper to manage the touch events but without success.
Here is my main activity code :

Xamarin Android Location updates not being called

I am trying to log location during an activity however I am not getting location updates. I have played around with the min refresh interval as well as the distance interval however it still doesn't work. I followed Xamarin's example for location updates but I've been banging my head against the wall as to why location updates arent working!

The PfgLocationInfo is just a simple class for holding the results
This works exactly as required and should be relatively easy to transform to your requirements.

It turns out this was working but very intermittently. The issue appeared to be that another thread that was running was asynchronously to log the sensor data was queueing up operations which were effectively drowning out the location updates.
Removing the sensor data logging started to allow location updates to come through. This seemed strange to me as this seemed to occur despite the sensor data logging being contained in their own thread.

Show 3dmodel after tracking lost metaio sdk

I am using metaio sdk 6.0.2. i am working on metaio INSTANT_2D_GRAVITY tracking and was able to display 3d model. I want to display same 3d model when tracking is lost.but I am failing to do so. I tried by adding trackingValuesVector in onTrackingEvent of MetaioSDKCallbackHandler with no success. can anyone tell me where am I going wrong?
private TrackingValues mTrackingValues;// declared globally
private IGeometry mModel; // declared globally
private boolean mPreview=true;// declared globally
// start INSTANT_2D_GRAVITY tracking
public void onTakePicture(View v)
{
captureTrackingValues = true;
metaioSDK.startInstantTracking("INSTANT_2D_GRAVITY", new File(""), mPreview);
mPreview = !mPreview;
}
final class MetaioSDKCallbackHandler extends IMetaioSDKCallback
{
#Override
public void onInstantTrackingEvent(final boolean success,final File filePath) {
super.onInstantTrackingEvent(success, filePath);
if(mSurfaceView != null)
{
mSurfaceView.queueEvent(new Runnable() {
#Override
public void run() {
if(success)
{
if(captureTrackingValues == true)
{
metaioSDK.setTrackingConfiguration(filePath);
Log.i("Tracking value success","good");
}
}
else
{
Log.i("Tracking value failure","bad");
}
}
});
}
}
#Override
public void onTrackingEvent(TrackingValuesVector trackingValuesVector) {
super.onTrackingEvent(trackingValuesVector);
if (!trackingValuesVector.isEmpty())
{
for(int i =0;i< trackingValuesVector.size();i++)
{
if(trackingValuesVector.get(i).isTrackingState() && mModel!=null)
{
mTrackingValues = metaioSDK.getTrackingValues(i);
mModel.setCoordinateSystemID(trackingValuesVector.get(i).getCoordinateSystemID());
}
else {
if(mModel!= null && mTrackingValues != null) {
metaioSDK.setCosOffset(1, mTrackingValues);
//mChairModel.setCoordinateSystemID(0);
Log.e("TestAR","isTrackingState is null");
}
}
}
}
else{
if(mModel!= null && mTrackingValues != null) {
metaioSDK.setCosOffset(1, mTrackingValues);
//mModel.setCoordinateSystemID(0);
Log.e("TestAR","trackingValuesVector is null");
}
}
}
}
loading 3d model:
private void loadModel()
{
if (mSurfaceView != null) {
mSurfaceView.queueEvent(new Runnable() {
#Override
public void run() {
File chairModel = AssetsManager.getAssetPathAsFile(getApplicationContext(),"chair.obj");
if (chairModel != null) {
mModel = metaioSDK.createGeometry(chairModel);
mModel.setScale(3f);
mModel.setTranslation(new Vector3d(0f,0f,-60f));
mGestureHandler.addObject(mModel, 1);
mModel.setRotation(new Rotation(0f, 0.5f, 0f));
mModel.setCoordinateSystemID(1);
}
}
});
}
else
{
Log.e("exception", "msurfaceview is null");
}
}

I see that you also tried setting the model to COS 0. This should actually work, if the tracking is lost.
If you do not see the model, you would have to play around with the scale value (i.e. set a low value like 0.01) and with the Z translation value. Set a negative Z value in order to move the model away from the camera clipping plane.

Osmdroid offline mode update tiles after zoom

I'm developing an Android app that uses Osmdroid to display the maps in offline mode. I have an issue when I want to zoom in or out by pinching on the map or using the build-in zoomcontrols. When I zoom in the map tiles are not always correctly rendered and when I zoom out the sometimes there are some gray tiles in the map, sometimes everything is rendered OK. It's not related on the location displayed on the map. My map tiles are stored in an osmdroid zip-file with the Mapnik source in the folder /mnt/sdcard/osmdroid. I'm using osmdroid-3.0.7.
So, any help is welcome.

I raised an issue on version 3.0.6 about this. In the comments the authors say it was fixed on Feb 1st. As the 3.0.7 jar is dated Jan 29, I assume the fix isn't in it. I'm sticking with version 3.0.5 for now, although the cycle maps don't work in it and the tile loading can be a bit flickery. If your maps are offline though, they should load pretty fast and flicker might not be an issue.

I'm not 100% sure if this is the same problem as reported here:
OSMDroid Google Group
If so then the solution (for now) seems to be to download the current OSMDroid source and build your own .jar library.
No changes to the source are required BUT the tile loading problem is fixed.
