我有一个难以解决的问题。我已经在Play上发布了我的应用程序,一切正常,但问题是有2台设备崩溃应用程序时出现以下错误:
java.lang.NoSuchMethodError: java.io.IOException.<init>
at com.google.android.gms.internal.g.f(Unknown Source)
at com.google.android.gms.internal.g.b(Unknown Source)

at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:561)
at java.lang.Thread.run(Thread.java:1096)
我只知道这个错误,因为Play告诉我,但是不可能看到它在哪里。此外,我有另一个信息。事情就是这样:当用户选择在抽屉菜单中查看地图并且错误是他第一次选择时,就会发生这种情况。
以下是此片段的代码:

崩溃的设备有:三星Galaxy ACE(GT-S5830B)和三星Galaxy 5(GT-I5500B)。提前谢谢,

stracktrace的第一行给你一个线索:
java.lang.NoSuchMethodError: java.io.IOException.<init>
基本上它说IOException
的某些构造函数丢失了。查看javadocs,API级别9中添加了两个构造函数:
public IOException (Throwable cause)
public IOException (String message, Throwable cause)
那应该回答你的问题。 API级别9是Android 2.3。因此,堆栈跟踪来自运行Android 2.2或更低版本的设备,缺少上面的两个构造函数。
至少有两种解决方案可以解决这个问题:
minSdkVersion
更改为9
。后者可以在SDK Manager中找到。它随last update一起添加,因为对Froyo(Android 2.2)的支持被删除了。引用链接的博客文章:
超过97%的设备现在运行Android 2.3(Gingerbread)或 更新的平台版本,我们正在放弃对Froyo的支持 发布Google Play服务SDK以使其成为可能 在未来提供更强大的API。这意味着你不会 能够在运行Android 2.2(Froyo)的设备上使用这些新API。
