Android Toast did not show after open Gallery and pick image

I want to show Toast (or progress bar) when clicking on the button "btnSearchImg". If before upload image, button clicked say "first pick image from gallary" and if after upload image clicked say "waiting". the toast before uploading image work fine but after uploading didn't work fine! my entire Activity code:
#Override

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_search_by_image);
Toasty.Config.getInstance().setTextSize(15).apply();
mSharedPreferences = getSharedPreferences("PREFERENCE", Context.MODE_PRIVATE);

mEditor.putString(PREF_SKIP,null);
if(mSharedPreferences.contains(PREF_SKIP)){
Log.i("payment", "true");
} else {

Thread t = new Thread(runner, "Code Executer");
t.start();
}
}
If I put the "Waiting..." Toast after the FindSimilarRequestedImage() the toast will show up, but I need the toast show immediately after clicking on the btnSearchImg.
NOTE: Also in the dateiLesenStringBuilder() I removed the thread t that this part of code runs in normal flow and serial, but nothing changes!

Instead of toast use logcat to see if they run sequentially or not, maybe toast takes time to run

I solved this problem by putting the part of code in delay like below:
private void FindSimilarRequestedImage() {
if (ivGalleryImgLoad.getDrawable() != null) {
pbImgRetrvialProccess.setVisibility(View.VISIBLE);
Toasty.success(getBaseContext(), "Waiting ...", Toast.LENGTH_LONG).show();
final Handler handler = new Handler();
handler.postDelayed(new Runnable() {
#Override
public void run() {
File loadedImageFilePath = new File(getRealPathFromURI(selectedImageUri));
queryFeatureX = uniformQuantization(loadedImageFilePath);
dateiLesenStringBuilder();
}
}, 5000);
} else {
Toasty.error(getBaseContext(), "first pick image from gallary", Toast.LENGTH_LONG).show();
}
}
Now before destroying activity throw functions, I first show the toast, then run other functions!

passing byte Array image into next Activity

My app consist Image Capture Face Recognition what i need to implement is converting the byte Array image into bitmap , and pass the bitmap to next Activity, The next Activity will receive the bitmap and show it in an image-view , than convert the bitmap into base 64.
I Don't know how to implement above task into my existing codes.
So when image is captured it shows, once click to save button pass the image to next activity and again convert the bitmap into base64.

Putin large data (>1Mo) can produce android.os.TransactionTooLargeException, ref :
The Binder transaction buffer has a limited fixed size, currently
1Mb, which is shared by all transactions in progress for the
process. Consequently this exception can be thrown when there are many
transactions in progress even when most of the individual transactions
are of moderate size.
The best way is to create a class and put your image into it, you can then access to it from any activity

Why dialog for enabling dangerous android permissions is shown 2 times?

I am developing an app where I am using android's dialog for granting dangerous permissions. And when I click button for login on LoginActivity I go to Main activity and dialog is show. But when I press BACK button, again this dialog appears! This is my MainActivity(Just to say that my launcher activity is MAinActivity, not LoginActivity):
