android 实现静默安装和卸载

通过获取系统root权限调用pm install -r apkpath 和pm uninstall pkgname 来实现.

附上代码：

[java] view
plaincopy

// install apk

private static void install(Activity activity, String path) {

Intent intent = new Intent(Intent.ACTION_VIEW);

intent.setDataAndType(Uri.fromFile(new File(path)),

"application/vnd.android.package-archive");

activity.startActivity(intent);

}

// uninstall a apk

private static void uninstall(Activity activity, String pkg) {

if (pkg == null) {

return;

}

Uri uri = Uri.fromParts("package", pkg, null);

Intent intent = new Intent(Intent.ACTION_DELETE, uri);

activity.startActivity(intent);

}

// install

public static void install_root(final Activity activity,final String path, final int msgwhat, final Handler callback) {

new Thread() {

public void run() {

Process process = null;

OutputStream out = null;

InputStream in = null;

try {

// 请求root

process = Runtime.getRuntime().exec("su");

if(callback!=null){

Message msg = new Message();

msg.what = msgwhat;

msg.obj = 0; //安装开始

callback.sendMessage(msg);

}

out = process.getOutputStream();

// 调用安装

out.write(("pm install -r " + path + "\n").getBytes());

in = process.getInputStream();

byte[] bs = new byte[256];

int len = in.read(bs);

if (-1 != len) {

//取得root成功

String state = new String(bs, 0, len);

SLog.e("test", "state = "+state);

if (state.equals("Success\n")) {

if(callback!=null){

Message msg = new Message();

msg.what = msgwhat;

msg.obj = 1; //安装成功

callback.sendMessage(msg);

}

}else {

if(callback!=null){

Message msg = new Message();

msg.what = msgwhat;

msg.obj = 2; //安装失败

callback.sendMessage(msg);

}

}

}else{

//取得root失败

install(activity,path);

}

} catch (IOException e) {

SLog.e("test", "IOException 1111 = ");

e.printStackTrace();

} catch (Exception e) {

SLog.e("test", "Exception 1111 = ");

e.printStackTrace();

} finally {

try {

if (out != null) {

out.flush();

out.close();

}

if (in != null) {

in.close();

}

} catch (IOException e) {

e.printStackTrace();

}

}

}

}.start();

}

public static void uninstall_root(final Activity activity,final String pkg,final int msgwhat, final Handler callback) {

new Thread() {

public void run() {

Process process = null;

OutputStream out = null;

InputStream in = null;

try {

// 请求root

process = Runtime.getRuntime().exec("su");

if(callback!=null){

Message msg = new Message();

msg.what = msgwhat;

msg.obj = 0; //卸载开始

callback.sendMessage(msg);

}

SLog.e("test", "111");

out = process.getOutputStream();

SLog.e("test", "222");

// 调用卸载

out.write(("pm uninstall " + pkg + "\n").getBytes());

SLog.e("test", "333");

in = process.getInputStream();

SLog.e("test", "444");

byte[] bs = new byte[256];

int len = in.read(bs);

SLog.e("test", "555 len = "+len);

if(-1 != len) {

//取得root成功

String state = new String(bs, 0, len);

SLog.e("test", "111 state = "+state);

if (state.equals("Success\n")) {

if(callback!=null){

Message msg = new Message();

msg.what = msgwhat;

msg.obj = 1; //卸载成功

callback.sendMessage(msg);

}

}else {

Message msg = new Message();

msg.what = msgwhat;

msg.obj = 2; //卸载失败

callback.sendMessage(msg);

}

}

}else {

//取得root失败

uninstall(activity,pkg);

}

} catch (IOException e) {

e.printStackTrace();

} catch (Exception e) {

e.printStackTrace();

} finally {

try {

if (out != null) {

out.flush();

out.close();

}

if (in != null) {

in.close();

}

} catch (IOException e) {

e.printStackTrace();

}

}

}

}.start();
