After onresume () is rewritten, super. onresume () is deleted. This exception can be added.
6. Sometimes the mobile phone cannot be connected and the ADB needs to be restarted.

Caused by: java.lang.ClassCastException: android.widget.LinearLayout$LayoutParams
Recently, when code is used in Android to dynamically change the height of a layout (component), an exception occurs in class conversion as shown in the question. I checked it online, as shown below:
These supply parameters toParentOf this view specifying how it shoshould be arranged. There are using subclasses of viewgroup. layoutparams, and these correspond to the different subclasses of viewgroup that are responsible for arranging their children.
So basically, if you are adding a view to another, you must set the layoutparams of the view to the layoutparams type that the parent uses, or you will get a runtime error.
I understand it in this way. If you want to add a view to another layout, you must set the layout parameters of this view to the layout parameter type used by its parent class. That is, to dynamically change the height of a component in the Code, the layout parameter type should be the layout parameter type used by its parent class.
View has set layoutparams, and its parent control also needs to be set
8. An exception is reported when three or more tabs are added to the tabhost.
Caused by: java.lang.IllegalArgumentException: you must specify a way to create the tab contentat android.widget.TabHost.addTab(TabHost.java:219)
According to the tabhost source code, we can see that mcontentstrategy = NULL.
Original statement
TabSpec ts1 = tabhost.newTabSpec(TAB1).setIndicator(TAB1);ts1.setContent(new Intent(BottomMenu_ArrowTop.this, TestViewFlipper.class));tabhost.addTab(ts1);
Written after Rewriting
tabhost.addTab(tabhost.newTabSpec(TAB1) .setIndicator(TAB1) .setContent(new Intent(this,TestViewFlipper.class)));
9. JNI method call error

There is no unimplementedstringfromjni method in JNI.
10. Custom Controls

11. Resource not found
04-13 11:06:00.460: ERROR/AndroidRuntime(25002): android.content.res.Resources$NotFoundException: String resource ID #0x1
At first, I thought it was strange that I couldn't do it after I cleaned it. Later I found that it was in textview. settext (position); It should be string, and the int written at that time
12. viewpager exception
Viewpager throws an exception after SDK upgrade
E/AndroidRuntime(6997): Caused by: java.lang.ClassNotFoundException: android.support.v4.view.ViewPager in loader dalvik.system.PathClassLoader[/data/app/cn.cmcc.brower.apk]
Place the third-party package in libs under the project directory, right-click the libs package, and set build
Select use as source folder in path, and then add the jar package to build path. Then, OK.
13. Unable to connect to the mobile phone
ADB server didn't ACK* failed to start daemon *
Turn Off 360 and restart eclipse. If the problem persists, uninstall pods and restart eclipse.
14. The illegalstateexception is invalid.
java.lang.IllegalStateException The specified child already has a parent. You must call removeView() on the child's parent first.
Adding a view instance to two la s throws this exception. You can add a new view to the second layout.
15. Prevent proguard from confusing third-party jar packages
-Keep public class package name .**{*;}
16. Android SDK manager cannot be updated
We only need to configure the hosts file and add the following sentence at the end of the file:
74.125.237.1 dl-ssl.google.com
In Windows, the hosts file is located at: c: \ windows \ system32 \ drivers \ etc. Find the file and open it in text format. Add the above sentence and close it after saving it, restart eclipse to open Android SDK manager. OK!
