转载自 Android 9 P静默安装/卸载App适配终极指南
引言
静默安装是指apk安装不需要用户手动点击，直接安装
安装流程
- 通过PackageManagerService获取getPackageInstaller对象
- 通过packageInstaller调用openSession创建PackageInstaller.Session
- 将要静默安装的app写入Session中
- 然后调用Session的commit开始安装
实现代码
public class InstallApkSessionApi extends Activity {
private static final String PACKAGE_INSTALLED_ACTION =
"com.xxx.install";
private static final String PACKAGE_UNINSTALLED_ACTION =
"com.xxx.uninstall";
private static final String TAG = "install";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_install_apk_session_api);
// Watch for button clicks.
Button button = (Button) findViewById(R.id.btn_install);
button.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
Log.d(TAG, "click ");
Thread thread = new Thread(new Runnable() {
@Override
public void run() {
PackageInstaller.Session session = null;
try {
//获取PackageInstaller对象
PackageInstaller packageInstaller = getPackageManager().getPackageInstaller();
PackageInstaller.SessionParams params = new PackageInstaller.SessionParams(
PackageInstaller.SessionParams.MODE_FULL_INSTALL);
//创建一个Session
int sessionId = packageInstaller.createSession(params);
Log.d(TAG, "sessionId = " + sessionId);
//建立和PackageManager的socket通道，Android中的通信不仅仅有Binder还有很多其它的
session = packageInstaller.openSession(sessionId);
//将App的内容通过session传输
addApkToInstallSession("hello.apk", session);
// Create an install status receiver.
Context context = InstallApkSessionApi.this;
Intent intent = new Intent(context, InstallApkSessionApi.class);
intent.setAction(PACKAGE_INSTALLED_ACTION);
PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent, 0);
IntentSender statusReceiver = pendingIntent.getIntentSender();
// Commit the session (this will start the installation workflow).
//开启安装
Log.d(TAG, "session.commit ");
session.commit(statusReceiver);
} catch (IOException e) {
throw new RuntimeException("Couldn't install package", e);
} catch (RuntimeException e) {
if (session != null) {
session.abandon();
}
throw e;
}
}
});
thread.start();
}
});
Button uninstall = (Button)findViewById(R.id.btn_uninstall);
uninstall.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
Thread thread = new Thread(new Runnable() {
@Override
public void run() {
uninstall("com.tony.usbcamera.molink");
}
});
thread.start();
}
});
}
private void addApkToInstallSession(String assetName, PackageInstaller.Session session)
throws IOException {
// It's recommended to pass the file size to openWrite(). Otherwise installation may fail
// if the disk is almost full.
try (OutputStream packageInSession = session.openWrite("package", 0, -1);
InputStream is = getAssets().open(assetName)) {
byte[] buffer = new byte[16384];
int n;
while ((n = is.read(buffer)) >= 0) {
packageInSession.write(buffer, 0, n);
}
}
}
// Note: this Activity must run in singleTop launchMode for it to be able to receive the intent
// in onNewIntent().
//此处一定要运行单例模式或者singleTop模式，否则会一直创建该Activity
@Override
protected void onNewIntent(Intent intent) {
Bundle extras = intent.getExtras();
Log.e(TAG, intent.toString());
if (PACKAGE_INSTALLED_ACTION.equals(intent.getAction())) {
Log.e(TAG, intent.getAction());
int status = extras.getInt(PackageInstaller.EXTRA_STATUS);
Log.d(TAG, "status = " + status);
String message = extras.getString(PackageInstaller.EXTRA_STATUS_MESSAGE);
switch (status) {
case PackageInstaller.STATUS_PENDING_USER_ACTION:
// This test app isn't privileged, so the user has to confirm the install.
Intent confirmIntent = (Intent) extras.get(Intent.EXTRA_INTENT);
startActivity(confirmIntent);
break;
case PackageInstaller.STATUS_SUCCESS:
Toast.makeText(this, "Install succeeded!", Toast.LENGTH_SHORT).show();
Log.e(TAG,"Install succeeded!");

}
}
else if(PACKAGE_UNINSTALLED_ACTION.equals(intent.getAction())){
Log.e(TAG, intent.getAction());
int status = extras.getInt(PackageInstaller.EXTRA_STATUS);
String message = extras.getString(PackageInstaller.EXTRA_STATUS_MESSAGE);
switch (status) {
case PackageInstaller.STATUS_PENDING_USER_ACTION:

Intent confirmIntent = (Intent) extras.get(Intent.EXTRA_INTENT);
startActivity(confirmIntent);
break;

}
}
/**
* 根据包名卸载应用
*
* @param packageName
*/
public void uninstall(String packageName) {
Intent broadcastIntent = new Intent(this, InstallApkSessionApi.class);
broadcastIntent.setAction(PACKAGE_UNINSTALLED_ACTION);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, broadcastIntent, PendingIntent.FLAG_UPDATE_CURRENT);
PackageInstaller packageInstaller = getPackageManager().getPackageInstaller();
packageInstaller.uninstall(packageName, pendingIntent.getIntentSender());
}
此时运行代码，会报错，找不到安装的apk，需要在 AS的main目录下创建一个 assets文件夹，把要安装的apk复制到这里面
AndroidManifest.xml配置
android:sharedUserId="android.uid.system" // 需要加这个
<uses-permission
android:name="android.permission.INSTALL_PACKAGES"
tools:ignore="ProtectedPermissions" />
<uses-permission android:name="permission.REQUEST_INSTALL_PACKAGES" />
<uses-permission android:name="permission.REQUEST_DELETE_PACKAGES" />
<uses-permission
android:name="android.permission.DELETE_PACKAGES"
tools:ignore="ProtectedPermissions" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_INSTALL_SESSIONS" />
<activity
android:name=".InstallApkSessionApi"
android:launchMode="singleTop"
android:exported="true">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
intent-filter>
activity>
android:sharedUserId="android.uid.system 是为了把apk打包成一个系统apk
android:launchMode=“singleTop” 需要添加，否则会一直创建该Activity
apk运行打包
放到源码目录下重新进行签名
编写Android.mk
LOCAL_PATH:= $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE := Test
LOCAL_MODULE_TAGS := optional
LOCAL_SRC_FILES := $(LOCAL_MODULE).apk
LOCAL_MODULE_CLASS := APPS
LOCAL_MODULE_SUFFIX := $(COMMON_ANDROID_PACKAGE_SUFFIX)
LOCAL_CERTIFICATE := platform
LOCAL_DEX_PREOPT := false
LOCAL_PROGUARD_ENABLED := disabled
include $(BUILD_PREBUILT)
LOCAL_MODULE 需要和apk的名称一致
编译
source build/envsetup.sh
lunch xxx
make Test -j8
