Android Question

Android Cannot resolve symbol OnRequestPermissionsResultCallback

I am new to android and I am trying to build an app to show my current location and I am following the setup in apidemos from google linked here. This is part of an assignment so I do not want to disclose what my ultimate goal is. For now I want to be able to have gps location working on my app. I will post my activity code, xml layout code, manifest code and gradle code. If there is anything else I need to post please let me know. I have tried searching but I couldn't find anything. Also if it helps I am mainly making this for my phone. Nexus 6p Android 6.0.1

EDIT:Got OnRequestPermissionsResultCallback Working but still have PermissionUtils giving me an error.

I will comment where my errors/cannot resolves are occurring

XML Code


<Button

android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="start|bottom"

android:layout_marginBottom="10dp"
android:paddingLeft="10dp"
android:onClick="start"/>
<Button

And here is my updated build gradle
apply plugin: 'com.android.application'

android {
compileSdkVersion 23
buildToolsVersion "23.0.2"

defaultConfig {
applicationId "com.example.name.app"
minSdkVersion 15
targetSdkVersion 23
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}

dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')
compile 'com.android.support:appcompat-v7:23.2.0'
compile 'com.google.android.gms:play-services:8.4.0'
compile 'com.android.support:support-v13:23.2.0'
}

Answer

Upgrade:

  • compileSdkVersion to 23
  • buildToolsVersion to 23.0.2
  • com.android.support:appcompat-v7 and com.android.support:support-v13 to 23.2.0

Your missing symbol is from a 23.x.y edition of appcompat-v7; the other changes are to keep the major version in sync.

Also, note that 7.5.0 is a rather old edition of play-services; I recommend upgrading that to 8.4.0.

And, bear in mind that all your runtime permission stuff is pointless, given targetSdkVersion 22.
