我想在我的应用程序中的静默更新,无需任何用户交互。 但是,我总是得到错误code 139。 硬件是根植! 任何人都可以帮忙吗?
I would like to have a silent update in my app without any user interaction. But I always get the error code 139. The hardware is rooted! Can anyone help?
下面是code:
public class UpdateAPK extends Activity {
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.updateapk);
if (isRooted() == true) {
Toast.makeText(UpdateAPK.this, "Hardware is rooted", Toast.LENGTH_LONG).show();
try {
Process install = Runtime.getRuntime().exec(new String[] {"su", "-c", "pm install -r /mnt/sdcard/app.apk"});
install.waitFor();
if (install.exitValue() == 0) {
// Success :)
Toast.makeText(UpdateAPK.this, "Success!", Toast.LENGTH_LONG).show();
} else {
// Fail
Toast.makeText(UpdateAPK.this, "Failure. Exit code: " + String.valueOf(install.exitValue()), Toast.LENGTH_LONG).show();
}
} catch (IOException e) {
System.out.println(e.toString());
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
} else {
//Do soemthing else
}
}
感谢您!
我想避免硬编码整个SD卡路径。尝试是这样的:
I'd avoid hard-coding entire SD card path. Try something like this:
String filePath = Environment.getExternalStorageDirectory().toString() + "/your_app_directory/your_app_filename.apk";
Process installProcess = null;
int installResult = -666;
try
{
installProcess = Runtime.getRuntime().exec("su -c pm install -r " + filePath);
}
catch (IOException e)
{
// Handle IOException the way you like.
}
if (installProcess != null)
{
try
{
installResult = installProcess.waitFor();
}
catch(InterruptedException e)
{
// Handle InterruptedException the way you like.
}
}
if (installResult == 0)
{
// Success!
}
else
{
// Failure. :-/
}
另外,要注意有关权限......你可以添加:
Also, be careful about permissions... You could add:
<uses-permission android:name="android.permission.ACCESS_SUPERUSER" />
