Android(安卓)apk安装的几种方法

1.使用linux命令安装：

apk事先保存在sdcard上面，如果安装不成功，可能权限不够，chmod 777一下，问题就解决了。

try {String cmd = "pm install -r sdcard/TestStartActivity_sig2.apk";Runtime.getRuntime().exec(cmd);} catch (IOException e) {// TODO Auto-generated catch blocke.printStackTrace();}

2.使用adb命令安装。

am start -n 包名/Activity所在包名及类名

adb shell am start -n com.liusl.test/com.liusl.test.MainActivity

3.使用发送Intent消息打开apk安装程序

public void installApk(String saveFileName) {File apkfile = new File(saveFileName);if (!apkfile.exists()) {Log.i(TAG, "installApk..file not exist!" + apkfile);return;}Intent i = new Intent(Intent.ACTION_VIEW);i.setDataAndType(Uri.parse("file://" + apkfile.toString()),"application/vnd.android.package-archive");mContext.startActivity(i);}

4.静默安装：安装过程中没有任何提示的安装

[1]重写pacakgemanager的相关类

IPackageDateObserver.java ,IPackageDeleteObserver.java,IPackageInstallObserver.java,IPackageMoveObserver.java,IPackageStateObserver.java,PackageManager.java

[2] 注册消息接收类

private static BroadcastReceiver mPackageInstallReceiver = new BroadcastReceiver() {     @Override     public void onReceive(Context context, Intent intent) {         String action = intent.getAction();         if (action.equals(UpdateManager.PACKAGE_INSTALL_SUCC)) {             Log.i(TAG, " receive .PACKAGE_INSTALL_SUCC");         } else {             Log.i(TAG, " receive .PACKAGE_INSTALL_FAILED.");         }    }};

[3]安装apk发送消息

private boolean installApkDefault(Context context, String fileName, String packageName) {        Log.d(TAG, "installApkDefault:" + packageName + ",fileName:" + fileName);File file = new File(fileName);int installFlags = 0;if (!file.exists())return false;installFlags |= PackageManager.INSTALL_REPLACE_EXISTING;PackageManager pm = context.getPackageManager();try {    IPackageInstallObserver observer = new MyPakcageInstallObserver(context, fileName,packageName);    Log.i(TAG, "installFlags:" + installFlags + "packagename:" + packageName);    pm.installPackage(Uri.fromFile(file), observer, installFlags, packageName);    return true;} catch (Exception e) {    Log.e(TAG, "installApkDefault fail ;exception: " + e.getMessage());}return false; }private class MyPakcageInstallObserver extends IPackageInstallObserver.Stub {Context cxt;String filename;String pkname;public MyPakcageInstallObserver(Context c, String filename, String packagename) {this.cxt = c;this.filename = filename;this.pkname = packagename;}@Overridepublic void packageInstalled(String packageName, int returnCode) {Log.i("MyPakcageInstallObserver", "returnCode = " + returnCode);// 返回1代表安装成功if (pkname != null && pkname.equals(packageName)) {Intent it = new Intent();it.putExtra("install_returnCode", returnCode);it.putExtra("install_packageName", packageName);if (returnCode == 1) {it.setAction(UpdateManager.PACKAGE_INSTALL_SUCC);} else {it.setAction(UpdateManager.PACKAGE_INSTALL_FAILED);File f = new File(filename);if (f.exists()) {f.delete();}}cxt.sendBroadcast(it);}}}
