Trying to pinpoint the errors on the Moto X

• [android] Crash when testing custom layer example #10152
• [android] Crash when testing animation types example #10151
• [android] Crash when testing user location drawable example #10150
• [android] Crash when swipping + zooming in building layer example #9935

Bisected the issue.

There are only 'skip'ped commits left to test.
The first bad commit could be any of:

#9009 seems to have introduced the issue

[ivovandongen]

Tried:

• Removing the glBufferSubData call -> no crash
• Going from glBufferSubData to glBufferData on updates -> crash
• Using GL_STATIC_DRAW -> crash
• Using a newly created vertex vector of the same length with empty elements -> crash
• Not binding the VertexBuffer passed in -> no crash, obviously renders weirdly
• Creating a new VertexBuffer -> no crash

Typical run, logging the creation and updating of the vertex buffers for line text:

Created buffer: 7 of size: 12288
Updating buffer: 7 of size: 12288
Created buffer: 10 of size: 13872
Created buffer: 13 of size: 11376
Updating buffer: 10 of size: 13872
Updating buffer: 7 of size: 12288
Updating buffer: 13 of size: 11376
Created buffer: 16 of size: 13440

Updating buffer: 16 of size: 13440
Updating buffer: 13 of size: 11376
Created buffer: 22 of size: 13152
Updating buffer: 22 of size: 13152
Updating buffer: 19 of size: 12288
Updating buffer: 16 of size: 13440
Updating buffer: 13 of size: 11376

The number of updates to the same buffer, the number of buffers created, the size of the buffer are all not fixed between manual runs.
