Android NDK GLThread _Android

归志宁无五亩园，读书本意在元元。这篇文章主要讲述Android NDK GLThread相关的知识，希望能为你提供帮助。
我正在尝试使用NDK在android中创建一个简单的动画，不幸的是我的代码抛出了Exception。
【Android NDK GLThread】A/libc: Fatal signal 11 (SIGSEGV), code 1, fault addr 0x0 in tid 16198 (GLThread 739)
我不知道这个错误是什么意思。
这些是我的一些代码。
Coin.cpp

void Coin::Render(GLuint textureId, GLuint positionHandle, GLuint texCoord, GLint matrixHandle, GLint samplerLoc) { // Bind the texture to this unit glBindTexture(GL_TEXTURE_2D, textureId); // Enable generic vertex attribute array glEnableVertexAttribArray(positionHandle); glEnableVertexAttribArray(texCoord); // Prepare the triangle coordinate data glVertexAttribPointer(positionHandle, 3, GL_FLOAT, GL_FALSE, 0, mVertices); // Prepare the texture coordinates glVertexAttribPointer(texCoord, 2, GL_FLOAT, GL_FALSE, 0, mUVCoord); // Apply the projection and view transformation glUniformMatrix4fv(matrixHandle, 1, GL_FALSE, 0); //Set the sampler texture unit to 0, where we have saved the texture glUniform1i(samplerLoc, 0); // Draw the triangle glDrawElements(GL_TRIANGLES, 6, GL_UNSIGNED_SHORT, mIndices); // Disable vertex array glDisableVertexAttribArray(positionHandle); glDisableVertexAttribArray(texCoord); }

这就是我声明我的数组Coin对象的方式，我认为它看起来像java中的

ArrayList<
Coin>

。
CoinRenderer.h

vector< Coin> mCoinCollection;

这是错误抛出的部分，代码在没有coin.Render()或coin.translate()的情况下工作，但是如果我取消注释这段代码代码不起作用。
CoinRenderer.cpp

void CoinRenderer::drawCoin() { // glUseProgram(programHandle); glUseProgram(imageHandle); long slowTime = GLUtils::currentTimeMillis() % 100000L; int elapse = (int) ((0.01f) * (slowTime)); for (int i = 0; i < mCoinCollection.size(); i++) { Coin coin = mCoinCollection[i]; if (mCurrentTime < elapse) { //int nextCoinFace = coin.getNextCoinFace(); //coin.setTextureId(textures[i]); // This is also the line where the error is throwing. //coin.translate(0.0f, 0.20f); } // This line where the error is throwing. coin.Render(coin.getTextureId(), mPositionHandle, mTexCoord, mMatrixHandle, mSamplerLoc); }if (!hasVisibleCoin()) { LOGD("All coins y < 0"); glDeleteProgram(imageHandle); }mCurrentTime = elapse; }

如果需要，这里有一些额外的代码。
CoinRenderer.kt

class CoinRenderer(private val context: Context) : GLSurfaceView.Renderer {override fun onDrawFrame(gl: GL10?) { nativeDrawFrame() }override fun onSurfaceChanged(gl: GL10?, width: Int, height: Int) { nativeSurfaceChange(width, height) }override fun onSurfaceCreated(gl: GL10?, config: EGLConfig?) { val assetManager = context.assets nativeSurfaceCreate(assetManager) }external fun nativeSurfaceCreate(assetManager: AssetManager) external fun nativeSurfaceChange(width: Int, height: Int) external fun nativeDrawFrame() external fun drawNewCoin(coinSize: Int) external fun nativeClearSurface(isClearSurface: Boolean)companion object { init { System.loadLibrary("coin-lib") } } }

CoinGL.kt

class CoinGL(context: Context) : GLSurfaceView(context) {private var mRenderer : CoinRenderer? = nullinit { // Set openGL version setEGLContextClientVersion(2)setZOrderOnTop(true) setEGLConfigChooser(8, 8, 8, 8, 16, 0) holder.setFormat(PixelFormat.RGBA_8888)mRenderer = CoinRenderer(context) setRenderer(mRenderer)renderMode = RENDERMODE_CONTINUOUSLY }fun drawNewCoin(coinSize: Int) { queueEvent ({ mRenderer?.drawNewCoin(coinSize) mRenderer?.nativeClearSurface(false) }) } }

PS：我只是Android OPENGL NDK或C ++中的新手，如果您发现或看到一些非常错误的声明或善意使用请向我解释。谢谢。
任何帮助将不胜感激。谢谢。
