Question

我有服务，只要应用程序处于活动状态就应该保持活动状态。因此，在LoginActivity用户未登录时，我调用stopService，当用户登录时，我启动服务显式查看startService。

public class LoginActivity extends BaseActivity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_login);

        if (accountHelper.isLoggedIn()) {
            proceedToMainActivity();
        } else if (savedInstanceState == null) {
            Fragment fragment = LoginFragment.newInstance();
            getSupportFragmentManager()
                    .beginTransaction()
                    .add(R.id.LoginContainer, fragment)
                    .commit();
        }
    }

    public void proceedToMainActivity() {
        final Intent intent = MainActivity.createIntent(this);
        intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);
        startActivity(intent);
    }
//...
}

然后在其他活动中，我在onStart中绑定并在onStop中取消绑定，在Service：

中

@Override
public boolean onUnbind(Intent intent) {
    Timber.d("onUnbind: %s", intent);
    handler.scheduleStop(KEEP_ALIVE);
    return false;
}

这将在KEEP_ALIVE时间之后安排stopSelf（）（现在是500（半秒），但60000（一分钟）就可以了））当用户长时间离开应用程序并成功重新创建时服务被破坏，但是在onCreate和onBind LeakCanary的非常短暂的时间之后报告此服务的内存泄漏。请注意，onUnbind和onDestroy都没有被调用。 LeakCanary提供以下转储：

为何服务标记为泄露？ UPD：我已经从onUnbind中删除了明确的服务启动/停止和延迟停止，但泄漏仍然是相同的。

Answer 1

看起来这对于有界服务来说是不可避免的。我已经制作了一个示例应用来演示此问题。 https://github.com/KonstantinBerkow/Android-Bound-Service-Leak

在onDestroy之前报告服务泄漏
