android.view.WindowManager$BadTokenException: Unable to add window -- token android.os.BinderProxy@8错误源: progressDialog=CustomProgressDialog.createDialog(context),ProgressDialog只能显示在Activity中
而不能显示在Context上下文上,所以更换为Activity的对象就解决。

Activity com.beidougd.bdg.activity.FragmentMainActivity has leaked IntentReceiver com.beidougd.bdg.activity.MainTabHomeNew$DeviceListReceiver@53c34078 that was originally registered here. Are you missing a call to unregisterReceiver()?错误源1:使用的是Fragment, 后来在重载Fragment的onDetach:
@Override public void onDetach() { super.onDetach(); if(viewFlipper!=null){ //防止android.app.IntentReceiverLeaked viewFlipper.stopFlipping(); } }即可解决。
错误源2:没有在注册广播后,取消注册广播。

.targetTabLabel加入TabHost中时会出现java.lang.IllegalStateException: The specified child already has a parent. You must call removeView() on the child's parent first.的异常错误源:
tabhost = getTabHost(); RelativeLayout tempLayout = (RelativeLayout) LayoutInflater.from(this).inflate(R.layout.mytab, null); TextView targetTabLabel = (TextView) tempLayout.findViewById(R.id.tab_text); targetTabLabel.setText("TAB 1"); tempLayout.removeAllViews(); tabhost.addTab(tabhost.newTabSpec("1").setIndicator(targetTabLabel).setContent(R.id.text1));要对tempLayout使用removeAllViews()。

java.lang.IllegalStateException: The application's PagerAdapter changed the adapter's contents without calling PagerAdapter#notifyDataSetChanged! Expected adapter item count: 4, found: 12 Pager id: com.beidougd.bdgc:id/viewPager Pager class: class android.support.v4.view.ViewPager Problematic adapter: class com.beidougd.bdg.util.SlideShowView$MyPagerAdapter
错误源:在快速加载网络数据时,由于获得的数据还没有适配在Adapter上,就快速切换Activity,处理方法是将此异常捕获,因为这种双手快速切换Activity的实例属于不正常现象,所以,我采用try{}Catch(Expection e){}
