安装失败现象
解决

前言

Android Debug Bridge (ADB) 是一个功能强大的命令行工具，用于与 Android 设备通信。
安装 APK 文件：

使用命令 adb install <apk文件路径> 可以将 APK 文件安装到设备上。
如果需要覆盖安装，可以使用 adb install -r <apk文件路径>。
如果需要降级安装，可以使用 adb install -d <apk文件路径>。
想要在安装时自动授予权限，可以使用 adb install -g <apk文件路径>。

调试android应用的过程, 突然出现安装失败的问题, 检查了各种环境, 重启了开发工具和目标设备依然无法解决.
在这里插入图片描述

安装失败现象

在AndroidStudio中尝试失败后, 又使用终端输入命令尝试:

adb install -r ~/adb/apk/Muzei.apk 
Performing Streamed Install
adb: failed to install /home/xxx/adb/apk/Muzei.apk: 
Exception occurred while executing:
java.lang.IllegalStateException: Too many active sessions for UID 2000at com.android.server.pm.PackageInstallerService.createSessionInternal(PackageInstallerService.java:523)at com.android.server.pm.PackageInstallerService.createSession(PackageInstallerService.java:420)at com.android.server.pm.PackageManagerShellCommand.doCreateSession(PackageManagerShellCommand.java:1380)at com.android.server.pm.PackageManagerShellCommand.runInstall(PackageManagerShellCommand.java:201)at com.android.server.pm.PackageManagerShellCommand.onCommand(PackageManagerShellCommand.java:109)at android.os.ShellCommand.exec(ShellCommand.java:96)at com.android.server.pm.PackageManagerService.onShellCommand(PackageManagerService.java:22745)at android.os.Binder.shellCommand(Binder.java:594)at android.os.Binder.onTransact(Binder.java:492)at android.content.pm.IPackageManager$Stub.onTransact(IPackageManager.java:2679)at com.android.server.pm.PackageManagerService.onTransact(PackageManagerService.java:3804)at android.os.Binder.execTransact(Binder.java:697)

从LOG中可以看到关键的报错信息:Too many active sessions for UID 2000:

按图索骥可以在对应的源码目录下查到LOG的源头:

frameworks/base/services/core/java/com/android/server/pm/PackageInstallerService.java

            final int sessionId;final PackageInstallerSession session;synchronized (mSessions) {// Sanity check that installer isn't going crazyfinal int activeCount = getSessionCount(mSessions, callingUid);if (mContext.checkCallingOrSelfPermission(Manifest.permission.INSTALL_PACKAGES)== PackageManager.PERMISSION_GRANTED) {if (activeCount >= MAX_ACTIVE_SESSIONS_WITH_PERMISSION) {throw new IllegalStateException("Too many active sessions for UID " + callingUid);}} else if (activeCount >= MAX_ACTIVE_SESSIONS_NO_PERMISSION) {throw new IllegalStateException("Too many active sessions for UID " + callingUid);}final int historicalCount = mHistoricalSessionsByInstaller.get(callingUid);if (historicalCount >= MAX_HISTORICAL_SESSIONS) {throw new IllegalStateException("Too many historical sessions for UID " + callingUid);}sessionId = allocateSessionIdLocked();}private static int getSessionCount(SparseArray<PackageInstallerSession> sessions,int installerUid) {int count = 0;final int size = sessions.size();for (int i = 0; i < size; i++) {final PackageInstallerSession session = sessions.valueAt(i);if (session.getInstallerUid() == installerUid) {count++;}}return count;}

    @GuardedBy("mSessions")private void writeSessionsLocked() {if (LOGD) Slog.v(TAG, "writeSessionsLocked()");FileOutputStream fos = null;try {fos = mSessionsFile.startWrite();XmlSerializer out = new FastXmlSerializer();out.setOutput(fos, StandardCharsets.UTF_8.name());out.startDocument(null, true);out.startTag(null, TAG_SESSIONS);final int size = mSessions.size();for (int i = 0; i < size; i++) {final PackageInstallerSession session = mSessions.valueAt(i);session.write(out, mSessionsDir);}out.endTag(null, TAG_SESSIONS);out.endDocument();mSessionsFile.finishWrite(fos);} catch (IOException e) {if (fos != null) {mSessionsFile.failWrite(fos);}}}

从代码中可以看到, 安装的过程中, 系统会记录下对应UID的安装数量等信息.

于是可以从设备端中查看记录的内容: /data/system/install_sessions.xml

rk3288:/data/system # cat install_sessions.xml
<?xml version='1.0' encoding='utf-8' standalone='yes' ?>
<sessions>
<session sessionId="4538363" userId="0" installerUid="2000" createdMillis="1358505151252" sessionStageDir="/data/app/vmdl4538363.tmp" prepared="true" sealed="false" mode="1" installFlags="4150" installLocation="1" sizeBytes="-1" originatingUid="-1" installRason="0" />

....

文件的内容很多, 这里只摘取了一部分.

回到源码中, 可以看到配置的SESSION数量: 1024

    /** Upper bound on number of active sessions for a UID that has INSTALL_PACKAGES */private static final long MAX_ACTIVE_SESSIONS_WITH_PERMISSION = 1024;/** Upper bound on number of active sessions for a UID without INSTALL_PACKAGES */private static final long MAX_ACTIVE_SESSIONS_NO_PERMISSION = 50;
