many thanks for your help

old activities which inherit from AppcompatActivity work fine. but if I create new one ,it get the error . here is my gradle.build :

apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.0"

    defaultConfig {
        applicationId "com.mkapp.apps.demo1"
        minSdkVersion 10
        targetSdkVersion 22
        compileOptions {
            sourceCompatibility JavaVersion.VERSION_1_7
            targetCompatibility JavaVersion.VERSION_1_7
        }
        multiDexEnabled true
    }
    dexOptions {
        incremental true
        javaMaxHeapSize "4g"
    }
    packagingOptions {
        exclude 'META-INF/LICENSE.txt'
        exclude 'META-INF/NOTICE.txt'
    }
    lintOptions {
        checkReleaseBuilds false
        // Or, if you prefer, you can continue to check for errors in release builds,
        // but continue the build even when errors are found:
        abortOnError false
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
        }
    }
}

dependencies {
    compile project(':photocollage')
    compile project(':gWFacebookSDK')
//    compile project(':listViewAnimation')
    compile 'com.google.android.gms:play-services:7.3.0'
    compile 'com.android.support:appcompat-v7:22.1.0'

    compile 'com.android.support:multidex:1.0.1'
    compile files('libs/aws-android-sdk-2.1.0-core.jar')
    compile files('libs/aws-android-sdk-2.1.0-sns.jar')

1.Just change your dependencies to present in the build.gradle--

dependencies {
    implementation fileTree(include: ['*.jar'], dir: 'libs')
    testImplementation 'junit:junit:4.12'
    implementation 'com.android.support:support-v4:23.4.0'
    implementation 'com.android.support:appcompat-v7:23.4.0'
    implementation 'com.android.support:support-annotations:27.1.1'
}

2.Then it will show to sync gradle, then sync build.gradle to update the changes.

Here's a cheesy solution, but it actually worked for me ! I manually created the needed path to the missing library :

 C:\Users\spomerleau\AppData\Local\Android\Sdk\extras\android\support\v7\appcompat\libs

and added the two missing .jar files from here and here. Android studio finally found the dependencies that needed to execute Java.

You need to Change your app build.gradle like this:

compile 'com.android.support:appcompat-v7:22.1.0+'

to

compile 'com.android.support:appcompat-v7:20.0.0'

You have this issue because you are trying to use onCreate (Bundle savedInstanceState, PersistableBundle persistentState), but this method is available only from API level 21.

I am able to reproduce the issue with this sample code on Android 4.4:

public class TourActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState, new PersistableBundle());
    }

    @Override
    public void onCreate(Bundle savedInstanceState, PersistableBundle persistentState) {
        super.onCreate(savedInstanceState, persistentState);
    }
}

And the issue is resolved removing every occurrence of PersistableBundle:

public class TourActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
    }
}

Check where you use PersistableBundle in your TourActivity and remove it or update your answer with the code of your activity.

The problem is that your TourActivity is using a class available only from API level 21 PersistableBundle. The question here is why is doing that.

Remember you new activity have to inherit from AppCompatActivity as well.

Quick question, are you overriding public void onSaveInstanceState(Bundle outState, PersistableBundle outPersistentState) in the problematic activity? If you are doing it you probably are saving a reference to PersistableBundle which is not available in the device/emulator. Try removing it if you are not doing nothing there or comment it to try...

Update your support library to 23 and your compileSdkVersion to 23 in build.gradle.

compileSdkVersion 23

...

compile 'com.android.support:support-v4:23.0.0'
compile 'com.android.support:appcompat-v7:23.0.0'

Then sync your project with gradle files.

Also, Google Play Services is now 7.8.0

First, update your libraries to the latest versions. Next, clean and rebuild your project.

Also, if this is a full list of libraries that you include:

    compile 'com.android.support:support-v4:22.2.1'
    compile 'com.google.android.gms:play-services:7.3.0'
    compile 'com.android.support:appcompat-v7:22.1.0+'
    compile 'com.android.support:multidex:1.0.1'

then you actually don't need to include this one

    compile 'com.android.support:multidex:1.0.1'
