我是android studio的新手,我正在开发我的第一个应用程序。
一切正常,直到我实现了启动画面。确实,当我运行该应用程序时,splashcreen起作用了,但是随后崩溃了。
问题是,启动画面不是我创建的第一个活动(主要活动)。我已经创建了我的应用程序,完成后,我添加了一个启动画面。
实际上,当我禁用启动画面(活动)并直接从上一个“启动时出现的活动”(即“菜单”)开始时,它可以正常工作。
一件奇怪的事情:启用启动画面后,它仅在某些设备上崩溃。它可以与我的Xiaomi Redmi Note 5和Galaxy S4(或nexus 5X模拟器)完美配合,但不能与Galaxy S3和S6完美配合。
我试图用一个简单的setonclicklistener按钮替换计时器。但是同样,当它必须加载菜单时,它会崩溃。
我没有在论坛上找到类似的问题,所以我在这里!

在您的应用gradle中,确保库使用相同的版本,例如:
implementation 'com.android.support:design:28.0.0-alpha1'
implementation 'com.android.support:cardview-v7:28.0.0-alpha1'
implementation 'com.android.support:appcompat-v7:28.0.0-alpha1'
implementation 'com.android.support:gridlayout-v7:28.0.0-alpha1'
您可能不需要全部。
进行更改,然后单击“立即同步”

解决了:
我必须将此添加到清单中
android:largeHeap="true"
效果很好。
