構造context繞過安全驗證，經過反射getBasePackageName識別構造context

//構造context，繞過通常包名簽名驗證。
try {
   CheckPermissionUtil.getSingInfo(
         this.createPackageContext("com.android.phone",
               Context.CONTEXT_INCLUDE_CODE | Context.CONTEXT_IGNORE_SECURITY));
} catch (PackageManager.NameNotFoundException e) {
   e.printStackTrace();
}

 

//獲取getBasePackageName包名 獲取context實際包名。
public static  String getBasePackageName(Context context) {
    String value = null;
    try {
        Class<?> c = Class.forName("android.content.Context");
        Method method = c.getMethod("getBasePackageName");

        method.setAccessible(true);//設置訪問權限
        value = (String) (method.invoke(context));
    } catch (Exception e) {
        e.printStackTrace();
    } finally {
        return value;
    }
}
