我正在尝试将此代码发送到WhatsApp,但是当它打开WhatsApp屏幕时,当我选择联系人时,我看不到任何图像。有人能帮我吗?
Bitmap adv = BitmapFactory.decodeResource(getResources(), R.drawable.image3);
Intent share = new Intent(Intent.ACTION_SEND);
share.setType("image/jpg");
ByteArrayOutputStream bytes = new ByteArrayOutputStream();
adv.compress(Bitmap.CompressFormat.JPEG, 100, bytes);
File f = new File(Environment.getExternalStorageDirectory()
+ File.separator + "temporary_file.jpg");
try {
f.createNewFile();
new FileOutputStream(f).write(bytes.toByteArray());
} catch (IOException e) {
e.printStackTrace();
}
Uri imageUri = Uri.parse(f.getAbsolutePath());
share.putExtra(Intent.EXTRA_STREAM, Uri.parse(Environment.getExternalStorageDirectory() + File.separator + "temporary_file.jpg"));
//share.putExtra(Intent.EXTRA_STREAM,Uri.parse("file:///android_asset/image3.jpg"));
if(isPackageInstalled("com.whatsapp",this)){
share.setPackage("com.whatsapp");
startActivity(Intent.createChooser(share, "Share Image"));
}else{
Toast.makeText(getApplicationContext(), "Please Install Whatsapp", Toast.LENGTH_LONG).show();
}
}
private boolean isPackageInstalled(String packagename, Context context) {
PackageManager pm = context.getPackageManager();
try {
pm.getPackageInfo(packagename, PackageManager.GET_ACTIVITIES);
return true;
} catch (PackageManager.NameNotFoundException e) {
return false;
}
}
