來自OpenGLRenderer的GL錯誤：0x502

我們的代碼在Canvas上執行非常簡單的操作（完全在UI線程中）：drawText，translate，save，restore。來自OpenGLRenderer的GL錯誤：0x502

偶爾，我們得到這個（在Nexus 4搭載4.3）：

W/Adreno200-ES20(22118): <gl_draw_error_checks:550>: GL_INVALID_OPERATION 
D/OpenGLRenderer(22118): GL error from OpenGLRenderer: 0x502 
E/OpenGLRenderer(22118): GL_INVALID_OPERATION

和相應的文本不會畫到畫布上。

一個問題是它隨機發生。該代碼可能無誤地工作10到20個電話，然後會出現這個錯誤，然後再次返回到正常工作的另一個10-20個電話。

不幸的是，你還沒有給出足夠的信息來真正回答這個問題......至少，你是否有一些GL API調用，假設你不能共享源代碼。 –

感謝您的提示。我編輯了這個問題。 –

您是否在onDraw（）中檢索的畫布上繪圖？ – Sipka

如果關閉硬件加速，這個錯誤不會發生。

在自定義視圖的構造函數：

setLayerType(View.LAYER_TYPE_SOFTWARE, null);

注：我不會接受這個答案（還），因爲它更是一個解決方法不是一個妥善的解決辦法。希望有更明確的東西...
