这个问题我看一下，能否提供复现的操作呢？

[diswy]

@qingmei2 这个主要也是友盟收集上来的BUG，感觉出现崩溃的概率比较高，这边暂时不知道如何复现，如果有用户反馈的上来我这边及时提交上来

[qingmei2]

@diswy

这个是2.5.4的bug吗，还是2.5.3就有的问题呢？

[diswy]

@qingmei2 2.5.3就有该BUG，2.5.4依旧存在

@diswy

谢谢你提供的信息，我会尝试尽快定位到问题并修复。

我用的2.5.1，刚看到友盟上也收集到相同的bug java.lang.RuntimeException: Unable to start activity ComponentInfo{com.xybaby.lucky/com.xybaby.imagepicker.ui.ImagePickerActivity}: kotlin.KotlinNullPointerException at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:3782) at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:3961) at android.app.servertransaction.LaunchActivityItem.execute(LaunchActivityItem.java:91) at android.app.servertransaction.TransactionExecutor.executeCallbacks(TransactionExecutor.java:149) at android.app.servertransaction.TransactionExecutor.execute(TransactionExecutor.java:103) at android.app.ActivityThread$H.handleMessage(ActivityThread.java:2386) at android.os.Handler.dispatchMessage(Handler.java:107) at android.os.Looper.loop(Looper.java:213) at android.app.ActivityThread.main(ActivityThread.java:8178) at java.lang.reflect.Method.invoke(Native Method) at com.android.internal.os.RuntimeInit$MethodAndArgsCaller.run(RuntimeInit.java:513) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:1101) Caused by: kotlin.KotlinNullPointerException at com.qingmei2.rximagepicker_extension.entity.SelectionSpec$Companion.getInstance(SelectionSpec.kt:127) at com.xybaby.imagepicker.ui.ImagePickerActivity.onCreate(Native Method) at android.app.Activity.performCreate(Activity.java:8086) at android.app.Activity.performCreate(Activity.java:8074) at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1313) at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:3755) ... 11 more kotlin.KotlinNullPointerException at com.qingmei2.rximagepicker_extension.entity.SelectionSpec$Companion.getInstance(SelectionSpec.kt:127) at com.xybaby.imagepicker.ui.ImagePickerActivity.onCreate(Native Method) at android.app.Activity.performCreate(Activity.java:8086) at android.app.Activity.performCreate(Activity.java:8074) at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1313) at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:3755) at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:3961) at android.app.servertransaction.LaunchActivityItem.execute(LaunchActivityItem.java:91) at android.app.servertransaction.TransactionExecutor.executeCallbacks(TransactionExecutor.java:149) at android.app.servertransaction.TransactionExecutor.execute(TransactionExecutor.java:103) at android.app.ActivityThread$H.handleMessage(ActivityThread.java:2386) at android.os.Handler.dispatchMessage(Handler.java:107) at android.os.Looper.loop(Looper.java:213) at android.app.ActivityThread.main(ActivityThread.java:8178) at java.lang.reflect.Method.invoke(Native Method) at com.android.internal.os.RuntimeInit$MethodAndArgsCaller.run(RuntimeInit.java:513) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:1101)

@qingmei2 不知大哥有空排查么，后台一直有这个问题在上报，应该是一个空指针引发的

[Roben1016]

@qingmei2 这个问题我这边复现过,但不是必现,在开发者模式中打开不保留活动, 然后打开图片选择的activity, 切换到其它应用, 然后重新返回APP偶尔重现, 是APP在相册页面被后台杀死后重新返回APP, 单例类SelectionSpec中的单例报空指针

[diswy]

这种有没有什么比较好的解决方案？

AndroidX项目使用2.5.6一点击就出现这个问题，后来仔细看了使用文档，使用3.0.0-beta02后可以正常使用
