小编cxp*_*ong的帖子

以下代码是否释放了分配给的内存x？

int main()
{
    char *x = (char*)calloc(100, sizeof(char));
    char *y = x;
    free(y);
}

每当我的应用程序启动时,都会在短时间内显示白色背景.尽管使用了启动画面,问题仍然存在.我想将启动屏幕设置为黑色而不是默认的白色!

这是我的启动画面活动:

public class SplashActivity extends Activity {

private static String TAG = SplashActivity.class.getName();
private static long SLEEP_TIME = 1;    // Sleep for some time

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    this.requestWindowFeature(Window.FEATURE_NO_TITLE);    // Removes title bar
    setContentView(R.layout.splash);

    // Start timer and launch main activity
    IntentLauncher launcher = new IntentLauncher();
    launcher.start();
}

private class IntentLauncher extends Thread {

    /**
      * Sleep for some time and than start new activity.
      */ 
    @Override
    public void run() {
        try {
            // Sleeping
            Thread.sleep(SLEEP_TIME*1000); …

错误GATT_INSUF_AUTHORIZATION是什么意思？我从TI CC2564发送了240044个字节,但是当android收到大约70000个字节时,Android显示错误GATT_INSUF_AUTHORIZATION.我看到问题只出现在带有CONNECTION_PRIORITY_HIGH的 Nexus 7上.

谢谢大家.

我使用 Pod 安装了一些存储库。我手动编辑了它们，所以我不想在将来安装新的存储库时更新它们。我使用“pod install --no-repo-update”但输出：

Re-creating CocoaPods due to major version update.

Pod 再次下载所有存储库
