如何处理此类OutOfMemoryErrors

Question

I'm testing my android App in some devices, and I've noticed a weird behavior in a certain mobile. When I open an Activity (which shows a bitmap) the first time it crashes generating this stack trace:

   java.lang.RuntimeException: Unable to start activity ComponentInfo{example.perifereia_hpeirou/com.epirus.MonumentProjection}: android.view.InflateException: Binary XML file line #2: Error inflating class <unknown>

However, if I try to open the activity again this doesn't happen.Also this doesn't occur in any other devices I've tested. I guess the mobile doesn't have enough ram atm and this exception helps it clean memory but this is just my guess.What can I do in order to overcome such a problem?

Answer 1

some ideas you can try:

a) Try with a small image to see if it is due to the size of the bitmap.

b) The first cause you have states:

Caused by: android.view.InflateException: Binary XML file line #2: Error inflating class <unknown>

I would also check if the class you are using here is supported by that particular device.

For example I remember an application I developed crashing with devices that weren't google certified because I assumed all devices would have google maps and this is not the case. I had to add a runtime check before instanciating the object.
