Integrate FirebaseUI to app/build.gradle cause crash at runtime

Adding
compile 'com.firebaseui:firebase-ui-auth:2.3.0'
into dependencies of the app/build.grandle File, cause an Error every Time I call FirebaseAuth.getInstance(). Before I added the new gradle Dependency, every FirebaseAuth.getInstance() Call works fine and also I was able to load Data from FirebaseDatabase.
Iam doing this Tutorial: FirebaseUI for Android — Auth. What did I wrong?
Update 1: Put the calls into an Try/Catch Block doesnt work. The Debbuger does not step into the catch Part.
UPDATE 2:
What is the Error? Answer: I dont get an Error. The Logcat Box do not print any Error Message. Also I cant figgure out the error via debugging, becaus the Catch-Block dont get reached.
My app/build.gradle:
dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
exclude group: 'com.android.support', module: 'support-annotations'
})
compile 'com.android.support:appcompat-v7:26.0.1'
compile 'com.android.support:design:26.0.1'
compile 'com.android.support.constraint:constraint-layout:1.0.2'
compile 'com.android.support:support-v4:26.0.1'
compile 'com.android.support:cardview-v7:26.0.1'
testCompile 'junit:junit:4.12'
//Firebase
compile 'com.google.firebase:firebase-auth:10.0.1'
compile 'com.google.firebase:firebase-database:10.0.1'
//FirebaseUI
compile 'com.firebaseui:firebase-ui-auth:2.3.0'
compile('com.facebook.android:facebook-android-sdk:4.22.1') // Required only if Facebook login support is required
}
apply plugin: 'com.google.gms.google-services'

To solve this, change this lines of code:
compile 'com.firebaseui:firebase-ui-auth:2.3.0'
with
compile 'com.firebaseui:firebase-ui-auth:1.2.0'

Make sure to using right version number for firebase-ui-auth at gradle. You can read the official document: https://firebase.google.com/docs/android/setup

Just check the compatibility:
FirebaseUI Version Firebase/Play Services Version
2.3.0 11.0.4
If you want to use the firebase-ui 2.3.0 you have to use firebase 11.0.4.
Use:
//Firebase
compile 'com.google.firebase:firebase-auth:11.0.4'
compile 'com.google.firebase:firebase-database:11.0.4'
//FirebaseUI
compile 'com.firebaseui:firebase-ui-auth:2.3.0'

Code for google's repo but gives error ->Failed to resolve: 'com.google.android.gms:play-services-appindexing:10.0.0'

/The above part of the code is there in the actual program/
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
testCompile 'junit:junit:4.12'
compile 'com.android.support:design:25.2.0'
compile 'com.github.bumptech.glide:glide:3.6.1'
compile 'de.hdodenhof:circleimageview:1.3.0'
compile 'com.android.support:appcompat-v7:25.2.0'
// Google
compile 'com.google.android.gms:play-services-auth:10.2.0'
// Firebase
compile 'com.google.firebase:firebase-database:10.0.0'

compile 'com.google.firebase:firebase-appindexing:10.0.0'
// Firebase UI
compile 'com.firebaseui:firebase-ui-database:0.4.0'
// Testing dependencies
androidTestCompile 'junit:junit:4.12'
androidTestCompile 'com.android.support.test.espresso:espresso-core:2.2.2'
androidTestCompile 'com.android.support.test:runner:0.5'
androidTestCompile 'com.android.support:support-annotations:25.2.0'
compile 'com.google.android.gms:play-services-appindexing:10.0.0'
}
apply plugin: 'com.google.gms.google-services'

Well If you look at releases, there isn't a 10.0.0 version. Only 10.0.1 and the recommended 10.2.0.
Also looking at the setup guide, app indexing isn't listed as one of the individual packages gps offers (though I'm not saying definitively that it does not exist), so maybe you should use the core package.
compile 'com.google.android.gms:play-services:10.2.0'

InstaBug, cannot resolve 'Builder'

Trying to implement InstaBug first time, however, when I initialize it,
new Instabug.Builder(this, "XXXXXXXXXXXXXXXXXXXX")
.setInvocationEvent(Instabug.IBGInvocationEvent.IBGInvocationEventShake)
.build();
Android Studio says cannot resolve symbol Builder
Though Builder extends from java.lang.Object , helpless to figure why this happens. Any fix?
EDIT:
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:23.1.1'
compile 'com.google.code.gson:gson:2.5'
compile 'com.android.support:recyclerview-v7:23.1.1'
compile "com.google.android.gms:play-services:8.4.0"
compile 'com.android.support:cardview-v7:+'
compile 'com.android.support:design:+'
compile 'com.squareup.picasso:picasso:2.5.2'
compile 'com.commit451:PhotoView:1.2.4'
compile 'net.danlew:android.joda:2.9.1'
compile project(":volley")
compile files('libs/YouTubeAndroidPlayerApi.jar')
compile ("com.instabug.library:instabugsupport:+") { exclude group: 'com.mcxiaoke.volley', module: 'library' }

Instabug.Builder was introduced in v2+ of Instabug SDK.
Can you try specifying the latest version of Instabug in your gradle, as follows:
compile('com.instabug.library:instabugcompat:2.2.1')
P.S: v2.2.1 was latest at the time of writing
P.S2: instabugcompat is the equivalent of instabugsupport in v2+
P.S3: Instabug doesn't include Volley anymore so you don't need to exclude it anymore
For more details, don't hesitate to ask. And you can check this out as well as #m-d mentioned

Android Studio cannot resolve symbol 'TabLayout'

Cannot resolve symbol TabLayout ? How to clear this error? Please help me. I already imported import android.support.design.widget.TabLayout;

Had a similar problem, to fix this in Android Studio (AS) I went Build->Clean Project and AS sorted everything out. Make sure in your build.gradle file under dependencies that you have:
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:your_api_version_number.0.0'
compile 'com.android.support:design:+'
}

I solved the issue Manually by adding the following two lines:
implementation 'com.android.support:support-v4:22.2.0'
implementation 'com.android.support:design:22.2.0'
under dependencies in \app\build.gradle worked for me.
Note: Your all the support libraries have to be the same version i.e. appcompat-v7 and support-v4 to same version e.g. 23.0.1; otherwise you can get this error
java.lang.NoClassDefFoundError: android.support.v7.internal.widget.TintManager`
after code build

Under Gradle Scripts,
Open build.gradle (Module: app)
Inside of dependencies add
compile 'com.android.support:design:25.3.1'
There may be a newer version of the library available, the android studio lint check may detect that.
The full dependencies area may look like this for reference. The above line is the only one I manually added.
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
exclude group: 'com.android.support', module: 'support-annotations'
})
compile 'com.android.support:appcompat-v7:25.3.1'
compile 'com.android.support.constraint:constraint-layout:1.0.2'
testCompile 'junit:junit:4.12'
compile 'com.android.support:design:25.3.1'
}
An above answer suggested adding
compile 'com.android.support:design:+'
Which is kind of dangerous because it always uses the latest library, you may have trouble isolating bugs with automatic library updates happening in the background.

Android Studio no longer uses "compile", they use "implementation".
Be sure to include the code below when you go to Build Gradle>dependencies{
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'com.android.support:appcompat-v7:27.1.1'
implementation 'com.android.support:support-v4:27.1.1'
implementation 'com.android.support:design:27.1.1'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:runner:1.0.1'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.1'
}

For Android API Level 29+, add the following dependency in build.gradle (Module:app):
dependencies {
implementation 'com.google.android.material:material:1.0.0'
}
If there is a newer version available, Android Studio will prompt you to use the newest one.

I solve it by Open build.gradle (Module: app) and add
implementation 'com.android.support:design:+'

Roboelectric 3.0 testing fragments

I am new to Roboelectric testing.
I am trying to follow this post to test fragments. I am using following as dependency
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
testCompile "org.robolectric:robolectric:3.0"
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:22.2.0'
compile 'com.google.code.gson:gson:2.3'
compile 'com.android.support:support-v4:22.1.0'
compile 'com.google.android.gms:play-services:7.5.0'
}
But this import is giving me compilation issues, and I am not able to resolve the symbol SupportFragmentTestUtil to start with. Kindly guide me what I am missing??
org.robolectric.shadows.support.v4.SupportFragmentTestUtil

You need to add the dependency for v4 shadows support. Add this in your dependency file.
testCompile "org.robolectric:shadows-support-v4:3.0"
