1, the SDK download is very slow.
Configure the SDK agent to be as fast as flying. It is recommended to finish the 20-24 first, or you will encounter many problems later.
2. The problem of SUPPORT-V7
For example Res\values\styles.xml:4: Error:error Retrieving parent for item:no Resource found that matches the given name ' Theme.a PpCompat.Light.DarkActionBar '.
Download the relevant toolkit, in fact, the beginning of the SDK has no amount, a lot of blog said there, I found a half-day.
Right-click on your project, there is an Android Tools below, clicking on add Support Lib ... , and then follow the prompts to download.
The rest is like other blogs that have been imported into the V7 project and the jar package.
3, V21 related issues
For example
Appcompat\res\values-v21\styles_base.xml:75:error:error Retrieving parent for item:no Resource found that matches the G Iven name ' Android:Widget.Material.ActionButton '.
To change in the V7 project, the target version of Project.Properties under the V7 project was changed a little higher.
4, cannot find the icon
For example Error:Error:No resource found that matches the given name (at ' icon ' with value ' @drawable/ic_launcher ').
Because the auto-generated mainfest file has its own icon under the drawable, but look closely at the folder without the picture resources, but under the mipmap
Change the icon path.
5. Something that should have been generated in R.
For example Activity_main cannot be resolved or was not a field
Remove import Android. R
6. Unable to preview layout
For example: This version of the rendering library was more recent than your version of ADT plug-in. Please update ADT plug-in
The ADT version is low, the SDK version is high, and the SDK version is lowered.
Probably that much, hope can help everybody
