please can ?

you should chech glerror after texture loading. on large amount of mobile gpu maximun texture size 2048x2048. have use textures sides power of 2(1024,2048,...). check glerror after texture loading , logcat(on devices easy see whats goes wrong gl in logcat). , draw large image use several small textures.
