項(xiàng)目中用OKhttp,在BaseActivity的onDestory方法中會取消當(dāng)前activity的請求,但是測試發(fā)現(xiàn)有的時候請求還是沒有取消

情況一

在Activity的請求成功回調(diào)中直接了下面代碼

        FragmentManager fragmentManager = getSupportFragmentManager();
        FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
        if (!fragment.isAdded()) {
            fragmentTransaction.add(R.id.drawer_content, fragment, CATEGORY_FRAGMENT);
        } else {
            fragmentTransaction.show(fragment);
        }
        fragmentTransaction.commitAllowingStateLoss();

當(dāng)Activity退出的時候,雖然在BaseActivity中寫了相應(yīng)的取消請求的方法,但是還是會報(bào)下面異常:

W: java.lang.IllegalStateException: Activity has been destroyed
W:     at android.support.v4.app.FragmentManagerImpl.enqueueAction(FragmentManager.java:1864)

W: Heartbeat timeout, GCM connection reset 0

情況二

對比情況一調(diào)用下面代碼

        FragmentManager fragmentManager = getSupportFragmentManager();
        FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
        if (!fragment.isAdded()) {
            fragmentTransaction.add(R.id.drawer_content, fragment, CATEGORY_FRAGMENT);
        } else {
            fragmentTransaction.show(fragment);
        }
        fragmentTransaction.commit();

則會報(bào)下面異常

W:     at android.support.v4.app.FragmentManagerImpl.checkStateLoss(FragmentManager.java:1842)

W:     at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:767)

解決

穩(wěn)定一點(diǎn)還是請求回調(diào)的時候判斷一下

if(isFinishing){
    return;
}
