helloworldAndroid应用程序在Akaso平板电脑上崩溃，但在glaxyS3手机上没有

Question

iv一直在使用Xe5编写一些Android应用程序，它们都在Galaxy S3上运行得很好。最近购买了一台运行Android 4.2.2的Akaso DTA90平板电脑？有什么想法吗？可能是解决方案问题？

我甚至试过一个基本的hello world应用程序，它也会崩溃

我的androidmanifest包含

    <?xml version="1.0" encoding="utf-8"?>

Answer 1

从您的logcat中可以看出，尽管清单包含写入外部存储的权限，但您的设备仍然不允许写入，可能是由于缺少外部存储（或模拟外部存储）：

W/ContextImpl( 7014): Unable to create external files directory

我现在不记得是什么原因导致Delphi启动想要写东西，但是如果你从项目fiule-use子句中删除StartupCopy单元，你可能会看到logcat的不同。。。。

Answer 2

假设您正在通过Eclipse进行Ad Hoc构建（运行方式->Android应用程序），只需打开LogCat视图（窗口->显示视图->其他，Android>LogCat），并在崩溃的平板电脑上发布错误追溯。

很可能是安卓版本错了，或者内存不足，或者你使用了一个不可用的功能，但如果没有回溯，我们就不会知道。
