安卓安全异常：应用已冻结

Question

有没有人看到过这个错误？应用程序在打开时立即崩溃，因为它无法启动默认活动。

Failure starting process com.xyz

Answer 1

您的应用程序可能会遇到“冻结帧”问题（请参见此处：https://developer.android.com/topic/performance/vitals/frozen.html）。如果您的应用程序中某个部分加载时间超过700毫秒，则会发生这种情况。建议查看Android Vital以了解是什么导致您的应用程序挂起。也许您在某个地方有一个无限循环。此外，请检查是否有除此之外的任何其他错误消息。

这不是导致错误的原因；请看我的答案，我会追踪这个错误消息来自哪里。 - mhansen

@mhansen，考虑到我的答案已经有4年了，而且Android SDK发展迅速，我会相信你的话。 - Janac Meena

Answer 2

你的包被冻结了，因为Android正在更新你的应用程序包（例如通过Play Store更新或adb install）。

错误来自PackageManagerService。

            case PACKAGE_STARTABILITY_FROZEN:
                throw new SecurityException("Package " + packageName + " is currently frozen!");

PACKAGE_STARTABILITY_FROZEN被定义在上面。

    /**
     * Used as the result code of the {@link Computer#getPackageStartability(boolean, String, int,
     * int)} to indicate the given package is <b>not</b> allowed to start because it's currently
     * frozen.
     */
    public static final int PACKAGE_STARTABILITY_FROZEN = 3;

这只会从ComputerEngine返回：

        if (mFrozenPackages.containsKey(packageName)) {
            return PackageManagerService.PACKAGE_STARTABILITY_FROZEN;
        }

这是在PackageFreezer中设置的：

/**
 * Class that freezes and kills the given package upon creation, and
 * unfreezes it upon closing. This is typically used when doing surgery on
 * app code/data to prevent the app from running while you're working.
 */
final class PackageFreezer implements AutoCloseable {

我的应用在一些本地代码中启动时出现了abort异常。

Answer 4

检查onCreate中的setContentView是否指向正确或现有的布局。

ex: setContentView(R.layout.activity_LAYOUTNAME);
