Contents

The CropImage activity extracted from Gallery.apk. Compatible with Android 2.1 onwards.

Refer to CropImage.java source code to learn about its Intent-based API.

Android 4 Notes

If your application targets Android 4 (API Level 14 and later) then it will use hardware acceleration by default. There's a bug in the CropImage activity which may trigger a Force Close error when hardware acceleration is enabled.

To work-around this bug you have to disable hardware acceleration for the CropImage activity by adding an entry like this in your AndroidManifest.xml:

<activity
    android:name="com.android.camera.CropImage"
    android:hardwareAccelerated="false"/>

Bug Details

On Android 4.0.0 and later, when hardware acceleration is enabled, the CropImage activity throws an unmanaged exception. The sources were imported from Android 2.1 and it is possible for some graphics operation to raise errors on newer platforms.
