 应用 默认加了systemUid和系统签名

广播在PMS里发送frameworks\base\services\core\java\com\android\server\pm\PackageManagerService.java

1.uninstall

Neither user 10083 nor current process has android.permission.REQUEST_DELETE_PACKAGES.

配置权限 

<!-- Allows an application to delete packages.
         <p>Not for use by third-party applications.
         <p>Starting in {@link android.os.Build.VERSION_CODES#N}, user confirmation is requested
         when the application deleting the package is not the same application that installed the
         package. -->
    <permission android:name="android.permission.DELETE_PACKAGES"
        android:protectionLevel="signature|privileged" />

<uses-permission android:name="android.permission.REQUEST_DELETE_PACKAGES"/>

public void uninstallApp(String packageName) {
        Intent intent = new Intent();
        intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        PendingIntent sender = PendingIntent.getActivity(getContext(), 0, intent, 0);
        PackageInstaller mPackageInstaller = getContext().getPackageManager().getPackageInstaller();
        mPackageInstaller.uninstall(packageName, sender.getIntentSender());// 卸载APK
    }

会收到  android.intent.action.PACKAGE_REMOVED 广播

2.disable

权限 

<!-- Allows an application to change whether an application component (other than its own) is
         enabled or not.
         <p>Not for use by third-party applications. -->
    <permission android:name="android.permission.CHANGE_COMPONENT_ENABLED_STATE"
        android:protectionLevel="signature|privileged" />

 public void disableApp(String packageName){
        PackageManager mPackageManager=getContext().getPackageManager();
        mPackageManager.setApplicationEnabledSetting(packageName,PackageManager.COMPONENT_ENABLED_STATE_DISABLED,PackageManager.DONT_KILL_APP);
    }

会收到 android.intent.action.PACKAGE_CHANGED 广播

3.enable

public void enableApp(String pkgName) {
        final PackageManager pm = mContext.getPackageManager();
        try {
            int state = pm.getApplicationEnabledSetting(pkgName);
           Log.d("TAG", "enableApplication state: " + state + " pkgName:" + pkgName);
            if (state == PackageManager.COMPONENT_ENABLED_STATE_ENABLED)
                return;
            pm.setApplicationEnabledSetting(pkgName, PackageManager.COMPONENT_ENABLED_STATE_ENABLED,
                    0);
        } catch (IllegalArgumentException exeption) {
            Log.w("TAG", "enableApplication error:" + exeption.getMessage());
        }
    }

会受到 android.intent.action.PACKAGE_CHANGED 广播 

4.install

    public boolean installApp(String packageName,String apkPath) {
        Process process = null;
        BufferedReader successResult = null;
        BufferedReader errorResult = null;
        StringBuilder successMsg = new StringBuilder();
        StringBuilder errorMsg = new StringBuilder();
        try {
            process = new ProcessBuilder("pm", "install", "-i", packageName, "-r", apkPath).start();
            successResult = new BufferedReader(new InputStreamReader(process.getInputStream()));
            errorResult = new BufferedReader(new InputStreamReader(process.getErrorStream()));
            String s;
            while ((s = successResult.readLine()) != null) {
                successMsg.append(s);
            }
            while ((s = errorResult.readLine()) != null) {
                errorMsg.append(s);
            }
        } catch (Exception e) {
        } finally {
            try {
                if (successResult != null) {
                    successResult.close();
                }
                if (errorResult != null) {
                    errorResult.close();
                }
            } catch (Exception e) {
            }
            if (process != null) {
                process.destroy();
            }
        }
        Log.e("result", "" + errorMsg.toString());
        //如果含有“success”认为安装成功
        return successMsg.toString().equalsIgnoreCase("success");
    }
