转到android AndroidManifest.xml

在你的文件是8

 < uses-sdk android：minSdkVersion =8/> 
 

将SDK版本更改为9，如下所示

 < uses-sdk android：minSdkVersion =9/> 
 

I am new to JSON. I followed this tutorial to create sample app. When i try to copy the code to my eclipse it show error.

Call requires API level 9 (current min is 8): android.os.StrictMode#setThreadPolicy

Please advice. Thanks

Go to the android AndroidManifest.xml

In your File it is 8

<uses-sdk android:minSdkVersion="8" />

Change The SDK version to 9 like shown below

<uses-sdk android:minSdkVersion="9" />
