Failed to resolve: com.google.android.gms:play-services in IntelliJ Idea with gradle

Credit goes to : StackOverflow

I had the issue when I put jcenter() before google() in project level build.gradle. When I changed the order and put google() before jcenter() in build.gradle the problem disappeared
Here is my final build.gradle

// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {

    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.1.3'


        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        google()
        jcenter()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

Failed to resolve: com.android.support:appcompat-v7:26.0.0

To use support libraries starting from version 26.0.0 you need to add Google's Maven repository to your project's build.gradle file as described here: https://developer.android.com/topic/libraries/support-library/setup.html

allprojects {
        repositories {
            jcenter()
            maven {
                url "https://maven.google.com"
            }
        }
    }

For Android Studio 3.0.0 and above:

allprojects {
        repositories {
            jcenter()
            google()
        }
    }

It's a lintValidRelease issue. You need an add lintOptions in Gradle file.

android {
..
     lintOptions {

        checkReleaseBuilds false

    }
}

• Thank You! that would work but what i did was that i connected to the internet when generating the signed Apk and by itself it did the magic – Micklo_Nerd Apr 2 at 8:56

  Adding lintOptions works, but it seems like a workaround. What is the root cause? I'm connected to the internet and it doesn't help. – 0xF Apr 5 at 18:42
• I would also like to find root cause for this. suddenly my CircleCi started throwing me this error Execution failed for task 'app:lintVitalRelease'. > Could not resolve all files for configuration 'app:lintClassPath'. > Could not find lint-checks.jar (com.android.tools.lint:lint-checks:26.1.2). Searched in the following locations: https://jcenter.bintray.com/com/android/tools/lint/lint-checks/26.1.2/lint-checks-26.1.2.jar – Rohit Karadkar May 28 at 14:54

How to avoid restarting activity when orientation changes on Android

Credit goes to StackOverflow

I am creating an Android app in which I'm drawing a view on a canvas. When the device's orientation changes, the activity restarts. I don't want it to.
How can I avoid restarting the activity when the orientation changes?
 

Define your activity in the AndroidManifest.xml like this:

   <activity
        android:name="com.name.SampleActivity"
        android:configChanges="keyboardHidden|orientation|screenSize"
        android:icon="@drawable/sample_icon"
        android:label="@string/sample_title"
        android:screenOrientation="portrait" >
    </activity>

How to go back to previous page if back button is pressed in WebView?

Credit goes to StackOverFlow

@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
    if (event.getAction() == KeyEvent.ACTION_DOWN) {
        switch (keyCode) {
            case KeyEvent.KEYCODE_BACK:
                if (mWebView.canGoBack()) {
                    mWebView.goBack();
                } else {
                    finish();
                }
                return true;
        }

    }
    return super.onKeyDown(keyCode, event);
}

=======================

For this code to work, you need to add a field to the Activity containing the WebView:
private WebView mWebView; Initialize it in the onCreate() method and you should be good to go.
mWebView = (WebView) findViewById(R.id.webView);

• were should I place that code? under all my code? or just under the loasUrl just like the builtinZoom? – zvzej May 20 '11 at 20:54

  You'd put it inside your activity, but outside the onCreate() method. – FoamyGuy May 20 '11 at 21:06
