Note: I have gone through all the related posts and did exactly what was written but nothing worked.
I am trying to add ConstraintLayout 1.1.0-beta1 for percent dimensions, but whenever I do this, a pop-up comes at the bottom which is below.
I clicked "Install Repositiory and Sync project" many times but nothing happened. So, I tried to add the following code in Build.gradle (Project) and it worked fine but a new error came.
repositories {
maven {
url 'https://maven.google.com'
}
}
The new Error is related to AppCompatTextView
The following class couldn't be instantiated :- android.support.v7.widget.AppCompatTextView
java.lang.NullPointerException

Whatever the above thing says can be removed by replacing ConstraintLayout 1.1.0-beta1 to ConstraintLayout 1.0.1 and the application works fine.
This is the build.gradle (app).
apply plugin: 'com.google.gms.google-services'
apply plugin: 'com.android.application'
android {
compileSdkVersion 26
buildToolsVersion "26.0.0"
defaultConfig {
applicationId "cant.reveal.the.secret"
minSdkVersion 17
targetSdkVersion 26
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
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-v7:26.+'
compile 'com.android.support:design:26.0.0-alpha1'
compile 'com.android.support.constraint:constraint-layout:1.1.0-beta1'
compile 'com.google.firebase:firebase-ads:11.0.4'
compile 'com.google.android.gms:play-services-maps:11.0.4'
compile 'com.google.android.gms:play-services-location:11.0.4'
compile 'com.readystatesoftware.sqliteasset:sqliteassethelper:+'
compile 'com.android.support:support-v4:26.+'
testCompile 'junit:junit:4.12'
}
So at last, Is there any solution/fix for this so I can use ConstraintLayout 1.1.0-beta1 with percent dimensions without this error.
Also, changing those 26.+ versions to 26.0.0 or 26.0.1 shows the same error.
EDIT -
What I've found out is whenever I add that Maven repo in my project gradle as described on Android support page, this rendering error comes.
Also, I can't see any of these versions I'm trying to add in SDK Mangager -> Tools which means addding these is not affecting the repo's versions and also not installing.
Where I can find .jar/.aar files of these libraries?
Still need help and Any help would be much appreciated. Thank you.
