title: Android Signed Apk crashed in below 5.0 Versions
body: <p>I create a signed APK and upload that, it crashes in all below version of marshmallow. The signed APK works on Android above version 5.0, but not on &lt;5.0. The AppCompat Library is linked with the project in Android.</p>
  
  <p>And when I normally run the same project in android 5.0 it work perfectly but signed apk not run in 5.0.</p>
  
  <p>And it was also not generating the crash report.</p>
  
  <p>In the AndroidManifest.xml I have declared:</p>
  
  <pre><code>android {
  compileSdkVersion 26
  buildToolsVersion '26.0.2'
  defaultConfig {
      applicationId "com.ahgp"
      minSdkVersion 21
      targetSdkVersion 26
      versionCode 1
      versionName "1.0"
      // Enabling multidex support.
      multiDexEnabled true
      testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
  }
  
  
  buildTypes {
      release {
          minifyEnabled false
          proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
      }
  }
  sourceSets { main { java.srcDirs = ['src/main/java', 'src/main/assets/fonts'] } }
