Android targetSdkVersion改成33遇到的坑

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 ， targetSdkVersion 改为 33 ，
导入 androidx 的基本包，示例对应的是 AppCompatActivity 、ConstraintLayout。

android {
    compileSdkVersion 33

    defaultConfig {
        targetSdkVersion 33
    }
}

dependencies {
    implementation 'androidx.appcompat:appcompat:1.5.0'
    implementation 'androidx.constraintlayout:constraintlayout:2.0.4'
}

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

编译报错，提示

We recommend using a newer Android Gradle plugin to use compileSdk = 33

This Android Gradle plugin (7.1.1) was tested up to compileSdk = 32

This warning can be suppressed by adding
    android.suppressUnsupportedCompileSdk=33
to this project's gradle.properties

The 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

support 包需要换成 androidx 的包，如

//import android.support.annotation.NonNull;
import androidx.annotation.NonNull;
//import android.support.v7.app.AppCompatActivity;
import androidx.appcompat.app.AppCompatActivity;

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.

wtf ？ 我都没有使用 PendingIntent 。

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。

多次尝试后，最后发现是导入了第三方库 work-runtime 导致的，升级库版本就好了。

-implementation "androidx.work:work-runtime:2.5.0"
+implementation "androidx.work:work-runtime:2.7.0"

如果有使用 PendingIntent ，改为

		PendingIntent pi;
		if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.S) {
			pi = PendingIntent.getActivity(mContext, 0, startIntent, PendingIntent.FLAG_IMMUTABLE);
		} else {
			pi = PendingIntent.getActivity(mContext, 0, startIntent, 0);
		}
