Yet it is not possible to post image in Instagram like FB or twitter.
But this is another way to achieve this using already installed Instagram and if not this will notify user to download app .
public void onClick(View v) {
Intent intent = getPackageManager().getLaunchIntentForPackage("com.instagram.android");
if (intent != null)
{
Intent shareIntent = new Intent();
shareIntent.setAction(Intent.ACTION_SEND);
shareIntent.setPackage("com.instagram.android");
try {
shareIntent.putExtra(Intent.EXTRA_STREAM, Uri.parse(MediaStore.Images.Media.insertImage(getContentResolver(), imagePath, "I am Happy", "Share happy !")));
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
shareIntent.setType("image/jpeg");
startActivity(shareIntent);
}
else
{
// bring user to the market to download the app.
// or let them choose an app?
intent = new Intent(Intent.ACTION_VIEW);
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.setData(Uri.parse("market://details?id="+"com.instagram.android"));
startActivity(intent);
}
}
