targetSdkVersion 改成 33 ，遇到一些坑。

需要注意的地方：

• 修改 targetSdkVersion 为 33。
• AndroidManifest.xml 里添加 android:exported=“true”
• 升级 Gradle 版本。
• 升级第三方库。

修改 app 的 build.gradle ，

android {compileSdkVersion 33defaultConfig {targetSdkVersion 33}
}

修改 AndroidManifest.xml ，为 activity 、service 等四大组件配置 android:exported="true" 。

编译报错，提示

We recommend using a newer Android Gradle plugin to use compileSdk = 33This Android Gradle plugin (7.1.1) was tested up to compileSdk = 32This warning can be suppressed by addingandroid.suppressUnsupportedCompileSdk=33
to this project's gradle.propertiesThe build will continue, but you are strongly encouraged to update your project to
use a newer Android Gradle Plugin that has been tested with compileSdk = 33

需要升级 Gradle 版本，修改 project 的 build.gradle ，

buildscript {repositories {google()mavenCentral()}dependencies {//classpath "com.android.tools.build:gradle:7.1.1"classpath "com.android.tools.build:gradle:7.4.2"// NOTE: Do not place your application dependencies here; they belong// in the individual module build.gradle files}
}

修改 gradle-wrapper.properties ，使用 gradle-7.5-bin.zip ，

#Thu Aug 08 18:55:44 CST 2024
distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
distributionUrl=https\://services.gradle.org/distributions/gradle-7.5-bin.zip
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists

编译OK，功能验证报错，

java.lang.IllegalArgumentException: com.xxx: Targeting S+ (version 31 and above) requires that one of FLAG_IMMUTABLE or FLAG_MUTABLE be specified when creating a PendingIntent.
Strongly consider using FLAG_IMMUTABLE, only use FLAG_MUTABLE if some functionality depends on the PendingIntent being mutable, e.g. if it needs to be used with inline replies or bubbles.at android.app.PendingIntent.checkFlags(PendingIntent.java:401)at android.app.PendingIntent.getBroadcastAsUser(PendingIntent.java:671)at android.app.PendingIntent.getBroadcast(PendingIntent.java:658)at androidx.work.impl.utils.ForceStopRunnable.getPendingIntent(ForceStopRunnable.java:273)at androidx.work.impl.utils.ForceStopRunnable.isForceStopped(ForceStopRunnable.java:151)at androidx.work.impl.utils.ForceStopRunnable.forceStopRunnable(ForceStopRunnable.java:171)at androidx.work.impl.utils.ForceStopRunnable.run(ForceStopRunnable.java:102)at androidx.work.impl.utils.SerialExecutor$Task.run(SerialExecutor.java:91)at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1137)at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:637)

wtf ？ 我都没有使用 PendingIntent 。

多次尝试后，最后发现是导入了第三方库导致的。

解决办法：更新第三方库。 旧版本的第三方库可能没有做 targetSdkVersion 33 的适配。
