android 禁止第三方apk安裝和解除安裝的方法詳解
阿新 • • 發佈：2020-11-15
需求是這樣的，客戶要求提供系統的介面來控制apk的安裝和解除安裝，介面如下
boolean setAppInstallationPolicies(int mode,String[] appPackageNames) mode：應用名單型別 0：黑名單(應用包名列表中的所有項都不允許安裝)； 1：白名單(只允許安裝應用包名列表中的項)。 appPackageNames：應用包名列表。當appPackageNames為空時，取消所有已設定的應用。 成功返回true；失敗返回false。 String[] getAppInstallationPolicies() 返回值為當前應用安裝管控狀態 string[0]：功能模式，參見setAppInstallationPolicies方法的mode引數。 string[1]至string[n-1]：應用包名列表。 boolean setAppUninstallationPolicies(int mode,String[] appPackageNames) mode：應用名單型別 0：黑名單(應用包名列表中的所有項均強制解除安裝)； 1：白名單(應用包名列表中的所有項禁止解除安裝)。 appPackageNames：應用包名列表。當appPackageNames為空時，取消所有已設定的應用。 成功返回true；失敗返回false。 String[] getAppUninstallationPolicies() 返回值為當前應用解除安裝管控狀態 string[0]：功能模式，參見setAppUninstallationPolicies方法的mode引數。 string[1]至string[n-1]：應用包名列表。
android版本為9.0，首先想到的是在系統裡面新增一個自己的service,分別在frameworks/base/core/java/android/app/新增IPolicyManager.aidl，frameworks/base/services/core/java/com/android/server/新增PolicyManagerService.java，在frameworks/base/新增policy/java/ga/mdm/PolicyManager.java，內容如下
package android.app;
/** {@hide} */
interface IPolicyManager
{
boolean setAppInstallationPolicies(int mode,inout String[] appPackageNames);
String[] getAppInstallationPolicies();
boolean setAppUninstallationPolicies(int mode,inout String[] appPackageNames);
String[] getAppUninstallationPolicies();

}
@Override
public boolean setAppInstallationPolicies(int mode,String[] appPackageNames){
if(mode==0){

}else if(mode==1){

}

}

}else{
return false;
}
mAppUninstallPackageNames = appPackageNames;
return true;
}
@Override
public String[] getAppUninstallationPolicies(){
return mAppUninstallPackageNames;
}
}
package ga.mdm;
import android.util.Slog;
import android.os.RemoteException;
import android.content.Context;
import android.app.IPolicyManager;
public class PolicyManager {
private final String TAG = "PolicyManager";

private final IPolicyManager mService;
public PolicyManager(Context context,IPolicyManager mService) {
mContext = context;
this.mService = mService;
}
public boolean setAppInstallationPolicies(int mode,String[] appPackageNames){
try {

} catch (RemoteException ex) {

return false;
}
}

return null;
}
}
public boolean setAppUninstallationPolicies(int mode,String[] appPackageNames){
try {
return mService.setAppUninstallationPolicies(mode,appPackageNames);
} catch (RemoteException ex) {
ex.printStackTrace();
return false;
}
}
public String[] getAppUninstallationPolicies(){
try {
return mService.getAppUninstallationPolicies();
} catch (RemoteException ex) {
ex.printStackTrace();
return null;
}
}
}
同時在frameworks/base/policy/新增Android.mk

這裡為什麼將PolicyManager.java單獨出來，因為PolicyManager.java是提供給客戶用的，單獨生成一個jar包，客戶只需要使用policy.jar就可以呼叫，同時需要新增

這樣就行了，燒錄重新開機使用adb shell service list可以看到新增的service
policy: [android.app.IPolicyManager]
在\out\target\common\obj\JAVA_LIBRARIES\policy_intermediates找到classes.jar，這就是提供給客戶用的jar
具體的禁止和解除安裝方法如下：
禁止安裝可以修改PackageManagerService.java，在handleStartCopy方法中新增下面的程式碼
public void handleStartCopy() throws RemoteException {
int ret = PackageManager.INSTALL_SUCCEEDED;
// If we're already staged,we've firmly committed to an install location
if (origin.staged) {
if (origin.file != null) {
installFlags |= PackageManager.INSTALL_INTERNAL;
installFlags &= ~PackageManager.INSTALL_EXTERNAL;
} else {
throw new IllegalStateException("Invalid stage location");
}
}
final boolean onSd = (installFlags & PackageManager.INSTALL_EXTERNAL) != 0;
final boolean onInt = (installFlags & PackageManager.INSTALL_INTERNAL) != 0;
final boolean ephemeral = (installFlags & PackageManager.INSTALL_INSTANT_APP) != 0;
PackageInfoLite pkgLite = null;
if (onInt && onSd) {
// Check if both bits are set.
Slog.w(TAG,"Conflicting flags specified for installing on both internal and external");
ret = PackageManager.INSTALL_FAILED_INVALID_INSTALL_LOCATION;
} else if (onSd && ephemeral) {
Slog.w(TAG,"Conflicting flags specified for installing ephemeral on external");
ret = PackageManager.INSTALL_FAILED_INVALID_INSTALL_LOCATION;
} else {
pkgLite = mContainerService.getMinimalPackageInfo(origin.resolvedPath,installFlags,packageAbiOverride);
//add by jueme
PolicyManager policyManager = (PolicyManager)mContext.getSystemService("policy");
String[] appNames = policyManager.getAppInstallationPolicies();
if(appNames!=null && appNames.length>0){
int app_status = android.provider.Settings.System.getInt(mContext.getContentResolver(),-1);
Slog.w(TAG,"app_status "+app_status);
if(app_status==0){
for (int i = 0; i < appNames.length; i++) {
Slog.w(TAG,"appNames 0 "+appNames[i]);
if (pkgLite.packageName.equals(appNames[i])){
ret = PackageManager.INSTALL_FAILED_INVALID_INSTALL_LOCATION;
break;
}
}
}else if(app_status==1){
for (int i = 0; i < appNames.length; i++) {
Slog.w(TAG,"appNames 1 "+appNames[i]);
if (pkgLite.packageName.equals(appNames[i])){
ret = PackageManager.INSTALL_SUCCEEDED;
break;
}else{
ret = PackageManager.INSTALL_FAILED_INVALID_INSTALL_LOCATION;
}
}
}
}
//add end
這樣在安裝時候就會報安裝位置不對的資訊。
接著是禁止解除安裝，在PackageInstallerService.java的uninstall新增下面的方法。
@Override
public void uninstall(VersionedPackage versionedPackage,String callerPackageName,int flags,IntentSender statusReceiver,int userId) throws RemoteException {
//add by jueme
PolicyManager policyManager = (PolicyManager)mContext.getSystemService("policy");
String[] appNames = policyManager.getAppUninstallationPolicies();
if(appNames!=null && appNames.length>0){
int appuninstall_status = android.provider.Settings.System.getInt(mContext.getContentResolver(),-1);
Slog.w(TAG,"appuninstall_status "+appuninstall_status+" mInstallerPackageName "+versionedPackage.getPackageName());
boolean isUninstall = true;//預設都是可解除安裝
if(appuninstall_status==0){
for (int i = 0; i < appNames.length; i++) {
if (versionedPackage.getPackageName().equals(appNames[i])){
isUninstall = true;
break;
}else{
isUninstall = false;
}
}
if(!isUninstall){
return;
}
}else if(appuninstall_status==1){
//應用包名列表中的所有項禁止解除安裝
for (int i = 0; i < appNames.length; i++) {
if (versionedPackage.getPackageName().equals(appNames[i])){
isUninstall = false;
break;
}else{
isUninstall = true;
}
}
if(!isUninstall){
return;
}
}
}
//add end
