Another solution is , set the minSdkVersion in your build.gradle as the one in your Phone.

Suppose your Phone version is Android 5.0 , then the API Level is 21. You can set the minSdkVersion 21.

defaultConfig {
    minSdkVersion 21
    targetSdkVersion 21
    versionCode 1
    versionName "1.0"
}

This will definetly work.

Try this:

if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.KITKAT) {
   // only for kitkat and newer versions
   android.app.AlarmManager.setExact(int type, long triggerAtMillis, PendingIntent operation);
} else {
   android.app.AlarmManager.set(int type, long triggerAtMillis, PendingIntent operation);
}

Basically, .setExact(...); method requires API 19 & above (it's just a way to bypass the optimization android provides, for maximizing battery life).
