主线程中的工作过多问题 warning.How 添加 AsyncTask?
Too much work in main thread issue warning.How add AsyncTask?
伙计们帮我添加异步任务 app.I 有问题添加 this.Maybe 任何提示如何实现 this.Its rtsp 视频 player.App 与网络服务器通信并使用 canvas.Async 任务绘制视频有助于解决主线程和跳过帧的问题?
if (frameNum >= skipNum) {
//Log.d(TAG, String.format("onFrame: nChannel = %d, width = %d, height = %d", nChannel, width, height));
try {
Canvas canvas = surface.lockCanvas(null);
try {
int area = width * height;
int pixels[] = new int[area];
for (int i = 0; i < area; i++) {
int r = frame[3 * i];
int g = frame[3 * i + 1];
int b = frame[3 * i + 2];
if (r < 0) r += 255;
if (g < 0) g += 255;
if (b < 0) b += 255;
pixels[i] = Color.rgb(r, g, b);
}
Bitmap bmp = Bitmap.createBitmap(pixels, width, height, Bitmap.Config.ARGB_8888);
canvas.drawBitmap(bmp, null, videoRect, null);
} finally {
surface.unlockCanvasAndPost(canvas);
}
} catch (Exception e) {
e.printStackTrace();
}
frameNum = 0;
}
}
不确定你 Android API 级别,但是 Async Task 现已弃用。
此 class 已在 API 级别 30 中弃用。
请改用标准 java.util.concurrent 或 Kotlin 并发实用程序。
由于您的代码是 Java,这里是并发的 link:https://developer.android.com/reference/java/util/concurrent/package-summary
