遇到一个程序，代码混淆，APK IDE查不到字符串，反编后的SAMLI全是a.smali db.smali之类，解压缩后没有SO文件，dex有300多KB，用IDA载入后找到很多ACTIVITY，如下：
FragmentActivity.<init>@V 0000AA8C 168 FragmentActivity.b@V 0000AAC0 173 FragmentActivity.a@V 0000AAD4 169 FragmentActivity.a@VI 0000AB00 170 FragmentActivity.a@VZ 0000AB40 171 FragmentActivity.b@LI 0000ABA4 172 FragmentActivity.onActivityResult@VIIL 0000ABE8 182 FragmentActivity.onBackPressed@V 0000ACB4 183 FragmentActivity.onConfigurationChanged@VL 0000ACDC 184 FragmentActivity.onCreate@VL 0000AD00 185 FragmentActivity.onCreatePanelMenu@ZIL 0000AD8C 187 FragmentActivity.onCreateView@LLLL 0000ADD8 188 FragmentActivity.onDestroy@V 0000B050 189 FragmentActivity.onKeyDown@ZIL 0000B08C 190 FragmentActivity.onLowMemory@V 0000B0CC 191 FragmentActivity.onMenuItemSelected@ZIL 0000B0F0 192 FragmentActivity.onPanelClosed@VIL 0000B14C 193 FragmentActivity.onPause@V 0000B184 194 FragmentActivity.onPostCreate@VL 0000B1AC 195 FragmentActivity.onPostResume@V 0000B1D0 196 FragmentActivity.onPreparePanel@ZILL 0000B1FC 197 FragmentActivity.onResume@V 0000B264 198 FragmentActivity.onRetainNonConfigurationInstance@L 0000B28C 199 FragmentActivity.onSaveInstanceState@VL 0000B340 200 FragmentActivity.onStart@V 0000B374 201 FragmentActivity.onStop@V 0000B438 202 FragmentActivity.startActivityForResult@VLI 0000B46C 203 请大师看看，如何确定哪个是关键的主ACTIVITY，并请讲讲还有什么高招可以解决此类软件，感谢 |
