android静默安装apk

首先必须获取root权限

通过pm命令执行安装操作

	public void install(String path) {

		try {
			Runtime runtime = Runtime.getRuntime();
			Process proc = runtime.exec("su");
			PrintWriter pw = new PrintWriter(proc.getOutputStream());
			pw.println("pm install -r " + path);
			pw.flush();
			pw.close();
			Log.v("Test", "install.path=" + path + " done");
		} catch (Exception e) {
			Log.v("Test", "install.path=" + path, e);
		}
	}
