Make sure that, if you're using eclipse, they're configured in the build path. That way it's included in the APK. Furthermore, your DroidQuiz.apk turns into DroidQuiz-1.apk because of how ADB transfers the file. It doesn't matter what you call the apk, it'll do the same thing.

I use Android Studio 3.0.1.
Device - Samsung Galaxy S4 GT-I9505 with Android 5.0.1.
From manifest file:
compileSdkVersion 26
buildToolsVersion '26.0.3'
minSdkVersion 21
targetSdkVersion 26
I have noticed that this can also occur when using bluetooth. When i turned bluetooth off so that my code stopped scanning i could capture the View Hierarchy just fine.
When i run my java code in the emulator or the real device, i every once in a while get this error. However, the app goes on and installs well. Since the error below appears in red text in my eclipse log, i have been forced to ask.. Is it an error that can cause significant problems when i release the app eventually or its something i should ignore? My guess is that i can use a try catch statement to capture the NullPointerException but i have no clue at what point in my MainActivity this error is generated.

I was following GCM Tutorial and I took utmost care in making no mistake and implementing same code in my project. But when I run the project I am getting ClassCast exception. I thought I would have missed something so I downloaded the source from that post and copied each and every line carefully in my project but still I am getting same exception. Please help solve the error.

I believe the problem is that you haven't set an Application name in your manifest.
Refer to this solution:
android classcastexception at android.app.Application
My android is W806 with MIUI system(andrid 2.3.4， could be downloaded at
http://119.147.150.88/gdown_group321/M00/01/BB/d5OWWE-TiE0AAAAABFRc6HZ-Izc1688998/MIUI_W806_updateEX.zip?k=rscjHEFnZBVxNvfDqVP3Iw&t=1355119512&u=712526008-27587528-bjpdc2a8&s=51200&file=MIUI_W806_updateEX.zip

I follow this example: http://mirnauman.wordpress.com/2012/01/30/using-google-maps-in-android-development-tutorial-part-1/, I have chosen Google API of 2.3.3 downloaded from SDK manager. But I got the problem Installation error: INSTALL_FAILED_MISSING_SHARED_LIBRARY.
I try to search solutions in google and stackoverflow, but no one fits me...I have some logcat, and here it is:

Looks like you are missing some information in your android project files and/or AndroidManifest.xml ?
Try and look at my earlier answer to a somewhat similar answers:
1. Answer
2. Answer
I am developing an Android app using fragments and would like the user to be able to pick an image for scanning purposes. I have a fragment that allows the user to select their desired source (camera, hand-drawn, or gallery). When the user selects Gallery, then another fragment should display the image. I already know how I am supposed to get the image into an ImageView but keep getting this error with the Fragments:

Basically it looks like there's an issue with my FragmentTransaction usage. Here's my code:
frag = new GalleryFragment();
frag.setImagePath(imagePath);
FragmentTransaction tx = getSupportFragmentManager().beginTransaction();
tx.replace(R.id.fragment_space, frag);
tx.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_FADE);
and my layout file:
<FrameLayout
android:id="#+id/fragment_space"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="65"/>
Never mind I figured this one out. It's the same solution as:
Android Fragment (with Compatibility Package on 2.3.3) creates "Specified child already has a parent error"
and
Error swapping / adding an XML Fragment
.
