java.lang.VerifyError: Verifier rejected class xxx: void xxx.<init>() failed to verify: void xxx.<init>(): [0x0] 

Constructor returning without calling superclass constructor (declaration of xxx' appears in /data/app/cn.qssq666.screendetection-2/base.apk)
        at xxx.m.Ce.checkEmulatorxxx(Hl)

对比混淆前后

.method public constructor <init>()V
    .locals 0

    .line 9
    invoke-direct {p0}, Ljava/lang/Object;-><init>()V

    return-void
.end method

混淆后删除了super()

# direct methods
.method public constructor <init>()V
    .locals 0

    return-void

原因是我为了删除日志工具类使用了高级混淆手段assumenosideeffects
而这个东西不能写通配符{*};否则会出现误删，具体看下面的文章

-assumenosideeffects class java.io.PrintStream {
    public *** println(...);
    public *** print(...);
}
-assumenosideeffects class android.util.Log {
    public static boolean isLoggable(java.lang.String,int);
    public static int v(...);
    public static int i(...);
    public static int w(...);
    public static int d(...);
   public static int e(...);
}


  -assumenosideeffects class qssq666.qssqtest.demo.test.Logs {

       *** <fields>;
        *** <methods>;
      public static void writeLog(...);
      public static String getLog(...);
      public static void clear(...);
      public static void writeErrorLog(...);
  }
  -assumenosideeffects class qssq666.qssqtest.demo.test.BuildConfig{
  *** <fields>;
  *** <methods>;
  }

  -assumenosideeffects class cn.qssq666.module.BuildConfig{
*** <fields>;
    *** <methods>;
  }

通配符改成 *** <fields>; 和 *** <methods>;
