android批量删除app开发学习

考虑到app批量卸载，每次卸载一个app都会弹出相应卸载界面

如果想在后如直接卸载，而不弹出界面

必须使用shell命令来执行卸载代码，也就是Linux命令

关于Java中使用Shell命令学习：

1，使用ProcessBuilder类来实现Shell命令构建与执行

2，使用ProcessBuilder的start()方法来执行Shell代码

3，执行后就可以得到执行结果InputStream

代码示例：

	private void excShell(String ...args) {
		ProcessBuilder pb = new ProcessBuilder(args);
		
		try {
			Process p = pb.start();
			InputStream inStream = p.getInputStream();
			Log.d(TAG, new String(convertInStream2String(inStream)));
		} catch (IOException e) {
			e.printStackTrace();
			finish();
		}	
	}
	
	byte[] convertInStream2String(InputStream inStream) {
		ByteArrayOutputStream b = new ByteArrayOutputStream();
		int count = 0;
		byte[] buffer = new byte[4096];
		try {
			while ((count = inStream.read(buffer)) > 0) {
				b.write(buffer, 0, count);
			}
		} catch (IOException e) {
			e.printStackTrace();
			finish();
		} finally {
			try {
				if(b != null) {
					b.close();
					b = null;
				}
			} catch (Exception e2) {
				e2.printStackTrace();
			}
		}
		return b.toByteArray();
	}

执行结果示例：

excShell("ps");
