As an Android coder, read more Android source code to improve the level of Android development is very helpful, then we can find out which way to view the Android source code?
1. If you can fq, go to the Android website to view the source code http://developer.android.com/reference/packages.html
2.http://androidxref.com/5.0.0_r2/
Androidxref can also view all versions of Android, just change the http://androidxref.com/5.0.0_r2 suffix 5.0.0_r2 to the appropriate version
3, Http://grepcode.com/project/repository.grepcode.com/java/ext/com.google.android/android/
Like Androidxref, Grepcode can also view various versions of Android, faster than Androidxref

5. View in IDE
Download the SDK version in SDK Manager
6. One Chrome kernel browser plugin:Android SDK Reference Search
This plugin can be searched directly into the extension center.
Https://chrome.google.com/webstore/search/Android%20SDK%20Reference%20Search%20
After installing this plugin you can go directly to the Android API official website: http://developer.android.com/reference/packages.html
To find a class casually: for example Activity:http://developer.android.com/reference/android/app/Activity.html

By tapping (view source), you can jump directly to the online official source code provided by Google:
Https://android.googlesource.com/platform/frameworks/base/+/refs/heads/master/core/java/android/app/Activity.java
