Android应用在Android 5之前的设备上崩溃

Question

我更新了我的SDK，播放服务等等，最近。当我在带有Lollipop前Android的设备/模拟器上运行我的应用程序时，它会立即出现以下错误：

我连火力点都不用！以下是我的分级：

apply plugin: 'com.android.application'
android {
    compileSdkVersion 24
    buildToolsVersion '24.0.1'
    lintOptions {
        checkReleaseBuilds false
        abortOnError false
    }
    defaultConfig {
        applicationId "com.Myapp"
        minSdkVersion 15
        targetSdkVersion 24
        versionCode 2
        versionName "2"
        multiDexEnabled true
    }
    buildTypes {
        release {}
    }
    productFlavors {
    }
    dexOptions {
        javaMaxHeapSize "4g"
    }
}

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    compile files('libs/Kryptonz-sdk.jar')
    compile 'com.android.support:appcompat-v7:24.1.0'
    compile 'com.squareup.okhttp3:okhttp:3.4.1'
    compile 'com.github.greenfrvr:hashtag-view:1.2.1'
    compile 'com.google.android.gms:play-services:9.2.1'
    compile 'com.android.support:cardview-v7:24.1.0'
    compile 'com.android.support:recyclerview-v7:24.1.0'
    compile 'com.android.support:multidex:1.0.1'
    compile 'com.nostra13.universalimageloader:universal-image-loader:1.9.4'
    compile 'com.android.support:support-v4:24.1.0'
    compile 'com.android.support:design:24.1.0'
}

您可以为Firebase添加依赖项

compile 'com.firebase:firebase-client-android:2.4.0'
