I am using the RootTools library to execute some shell commands on my android App.
However I need to wait for the commands to finish before proceeding. The documentation shows a waitForFinish() method which is not available on the latest version of the library at least.
How would I accomplish a similar behaviour?
This work for me:
First you must instace the command without enabling the handler (with false):
Command command = new Command(0, false, "cat")
Next do something like this:
RootTools.getShell(true).add(command);
while (!command.isFinished())
{
try
{
Thread.sleep(50);
}
catch (InterruptedException e)
{
// TODO Auto-generated catch block
e.printStackTrace();
}
}

I'm building a DPC (Device Policy Controller), and one of the issues I'm seeing is that while the Play Store and Play Services are being updated, the Google Contact Sync service crashes -- leaving the typical crash dialog on the screen. Since part of the idea of the initial set up process is to have as little user interaction as possible, how can I dismiss this dialog programmatically (since I seem to be pretty much guaranteed that this will happen)?
I've tried dismissing system dialogs...
ctx.sendBroadcast(new Intent(Intent.ACTION_CLOSE_SYSTEM_DIALOGS));
... but that doesn't seem to do the trick.
Since this is a DPC, anything that requires device ownership/administration is fine.
edit: Usually I have no UI on screen at the time, so if one is necessary please do mention it. Also, preferably the solution should work on at least 6.0+, if not 4.0+.
Try to do it onWindowsFocusChanged method like this for example :
#Override
public void onWindowFocusChanged(boolean hasFocus) {
super.onWindowFocusChanged(hasFocus);
if (!hasFocus) {
Intent ctx= new Intent(Intent.ACTION_CLOSE_SYSTEM_DIALOGS);
sendBroadcast(ctx);
}
}
I'm not sure about app crash Dialog but maybe it'll help you
AppErrorDialog can be dismissed by broadcasting ACTION_CLOSE_SYSTEM_DIALOGS if Android version is N.
ctx.sendBroadcast(new Intent(Intent.ACTION_CLOSE_SYSTEM_DIALOGS));
However, AppErrorDialog won't be displayed if phone is locked.
public boolean canShowErrorDialogs() {
return mShowDialogs && !mSleeping && !mShuttingDown
&& mLockScreenShown != LOCK_SCREEN_SHOWN;
} // ActivityManagerService
Please try this code.
try {
Class ActivityManagerNative = Class.forName("android.app.ActivityManagerNative");
Class IActivityManager = Class.forName("android.app.IActivityManager");
Method getDefault = ActivityManagerNative.getMethod("getDefault", null);
Object am = IActivityManager.cast(getDefault.invoke(ActivityManagerNative, null));
Method closeSystemDialogs = am.getClass().getMethod("closeSystemDialogs", String.class);
closeSystemDialogs.invoke(am, "DPC close");
} catch (ClassNotFoundException e) {
e.printStackTrace();
} catch (NoSuchMethodException e) {
e.printStackTrace();
} catch (InvocationTargetException e) {
e.printStackTrace();
} catch (IllegalAccessException e) {
e.printStackTrace();
}
In my Android app, when the following code is successful:
mDbxAcctMgr.startLink(SyncActivity.this,REQUEST_LINK_TO_DBX);
This code runs:
if (ds.getSyncStatus().hasIncoming) {
try {
Map<String, Set<DbxRecord>> mMap = mDatastore
.sync();
dataHasIncoming(mMap); // Inserted into the database
} catch (DbxException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
If you close the app while this is occurring, dataHasIncoming(mMap) just inserts part of the data, but loses the rest. Is there any way around this, such as setting a node, or re-opening the synchronization without checking all the data?
I have a Robotium test case and It should be like
UI Application starts uploading data to server
User swaps to some other application on the device
uploading operation is running at the background
user comes to the main UI application
How to keep track of uploading the data at background? can we use multithreading for this?
try {
mSolo.clickOnMenuItem("UPLOAD");
mSolo.sleep(1000);
Instrumentation inst = new Instrumentation();
inst.sendKeyDownUpSync(KeyEvent.KEYCODE_BACK);
mSolo.waitForActivity(Settings.ACTION_APPLICATION_SETTINGS);
mSolo.goBack();
mSolo.assertCurrentActivity("main",
UIActivity.class);
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
Is this code correct? If not suggest me a modification or correct code.
Help is always appreciated,
Thanks
You cannot interact with other applications unless you signed the third party application with your own key (see black box testing).
But what you can is pressing Home, Back and starting Intents. The following code is untested but hopefully gives you an idea:
try {
mSolo.clickOnMenuItem("UPLOAD"); // start upload
mSolo.sleep(1000);
mSolo.goBack(); // leave app
...
Intent intent = new Intent("com.company.another.app.SomeActivity");
startActivity(inent); // start another app
...
// option one: get app context and use it for access on preferences, etc.
Context context = this.getInstrumentation().getTargetContext().getApplicationContext();
// option two: wait for logs that you write while uploading
solo.waitForLogMessage("Upload completed");
...
Intent intent = new Intent("com.myapp.MyMainUIActivity");
startActivity(inent); // start own Main Activity again
...
} catch (Exception e) {
e.printStackTrace();
}
So you could use log messages, preferences or any other methods of your app in order to follow up the upload progress.
You cannot leave your application and run it again with Instrumentation. This part is not correct:
Instrumentation inst = new Instrumentation();
inst.sendKeyDownUpSync(KeyEvent.KEYCODE_BACK);
Why do you create new instrumentation? You can simply run:
getInstrumentation().sendKeyDownUpSync(KeyEvent.KEYCODE_BACK);
by the way, solo.goBack() just does it, so it doesn't make sense to call it with instrumentation. I would simply rewrite it to:
try {
mSolo.clickOnMenuItem("UPLOAD");
mSolo.sleep(1000);
mSolo.goBack();
assertTrue(mSolo.waitForActivity(Settings.ACTION_APPLICATION_SETTINGS));
mSolo.goBack();
mSolo.assertCurrentActivity("main", UIActivity.class);
} catch (Exception e) {
e.printStackTrace();
}
I want to implement a silent installer-from-apk-file and unistaller-package in Android.
The topic has largely been discussed on SO and elsewhere but I can't apply any for some reason that I'm missing.
The scope is obviously hard to achieve because, if successful, it would be a serious security breach in Android. BUT, I need to implement it for a special project, not for the consumer market.
There are two approaches:
to generate a custom ROM from a source code (AOSP or Cyanogen mod, for example), by tweaking the PackageManager installer (in fact just to remove the user acceptance dialog boxes).
to do it programmatically by creating a process as super user and executing an 'adb shell pm install'. I previously installed 'su' in /system/xbin and I test during run time that RootTools.rootIsAvailable().
For the first case, I digged into the Froyo source code but got into a dead end with a #hide marked method.
For the second I've first tried the commands from the terminal
adb shell pm install /mnt/sdcard/HelloAndroid.apk
and
adb shell pm uninstall com.example.helloandroid
Both work OK. Then, I used the following code, the development being tested on a rooted emulator (2.2 - Froyo):
#Override
public void onClick(View v) {
switch (v.getId())
{
case R.id.btnInstall:
try {
install = Runtime.getRuntime().exec("su\n");
DataOutputStream os = new DataOutputStream(install.getOutputStream());
os.writeBytes("pm install /mnt/sdcard/HelloAndroid.apk\n");
os.writeBytes("exit\n");
os.flush();
install.waitFor();
if (install.exitValue() == 0) {
Toast.makeText(MainActivity.this, "Success!", Toast.LENGTH_LONG).show();
}
else {
Toast.makeText(MainActivity.this, "Failure. Exit code: "+String.valueOf(install.exitValue()), Toast.LENGTH_LONG).show();
}
}
catch (InterruptedException e) {
logError(e);
}
catch (IOException e) {
logError(e);
}
break;
case R.id.btnUninstall:
try {
install = Runtime.getRuntime().exec("su\n");
install=Runtime.getRuntime().exec("pm uninstall "+txtPackageName.getText().toString()+"\n");
} catch (Exception e) {
logError(e);
}
break;
}
}
To avoid typos and other trims I hardcoded the apk file parameter of the command for the installation; on 'case R.id.btnInstall' the command is not executed and the exit is on "Failure" with exit value 1, meaning that "the class cannot be found"; no clue what that means ...
I appreciate your help!
EDITED: I have the clean solution, I shall post the answer from A-Z as soon as I have the time and the code in the right form!!
As I promised here is the solution to this problem, without doing any forcing to the system other than having to install the whole application in the /system/app directory. I have followed, then did some fixing to the excellent article here: http://paulononaka.wordpress.com/2011/07/02/how-to-install-a-application-in-background-on-android/. I have downloaded the zip file referenced in the article then, (I tried to keep the same class names where possible):
created a new project and a main activity as entry point
package com.example.silentinstuninst;
import java.io.File;
import java.lang.reflect.InvocationTargetException;

import android.app.Activity;
import android.util.Log;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;
public class MainActivity extends Activity implements OnClickListener {
Process install;
Button btnInstall, btnUninstall;
EditText txtApkFileName, txtPackageName;
public static final String TAG = "SilentInstall/Uninstall";
private static ApplicationManager am;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
initializeValues();
}
private void initializeValues() {
btnInstall = (Button) findViewById(R.id.btnInstall);
btnUninstall = (Button) findViewById(R.id.btnUninstall);
txtApkFileName = (EditText) findViewById(R.id.txtApkFilePath);
txtPackageName = (EditText) findViewById(R.id.txtPackageName);
btnInstall.setOnClickListener(this);
btnUninstall.setOnClickListener(this);
try {
am = new ApplicationManager(this);
am.setOnInstalledPackage(new OnInstalledPackage() {
public void packageInstalled(String packageName, int returnCode) {
if (returnCode == ApplicationManager.INSTALL_SUCCEEDED) {
Log.d(TAG, "Install succeeded");
} else {
Log.d(TAG, "Install failed: " + returnCode);
}
}
});
am.setOnDeletedPackage(new OnDeletedPackage() {
public void packageDeleted(boolean succeeded) {
Log.d(TAG, "Uninstall succeeded");
}
});
} catch (Exception e) {
logError(e);
}
}
private void logError(Exception e) {
e.printStackTrace();
Toast.makeText(this, R.string.error+e.getMessage(), Toast.LENGTH_LONG).show();
}
#Override
public void onClick(View v) {
switch (v.getId())
{
case R.id.btnInstall:
// InstallUninstall.Install(txtApkFileName.getText().toString());
try {
am.installPackage(Environment.getExternalStorageDirectory() +
File.separator + txtApkFileName.getText().toString());
} catch (IllegalArgumentException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
} catch (IllegalAccessException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
} catch (InvocationTargetException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
} // install package
break;
case R.id.btnUninstall:
// InstallUninstall.Uninstall(txtPackageName.getText().toString());
try {
am.uninstallPackage(txtPackageName.getText().toString());
} catch (IllegalArgumentException e) {
// TODO Auto-generated catch block
e.printStackTrace();
logError(e);
} catch (IllegalAccessException e) {
// TODO Auto-generated catch block
e.printStackTrace();
logError(e);
} catch (InvocationTargetException e) {
// TODO Auto-generated catch block
e.printStackTrace();
logError(e);
}
break;
}
}
}
create in /src the package com.example.instuninsthelper. I have added there the ApplicationManager.java and OnInstalledPackage.java files
inserted the following code inside the ApplicationManager class:
private OnDeletedPackage onDeletedPackage;
class PackageDeleteObserver extends IPackageDeleteObserver.Stub {
public void packageDeleted(boolean succeeded) throws RemoteException {
if (onDeletedPackage != null) {
onDeletedPackage.packageDeleted(succeeded);
}
}
}
created, under the same com.example.instuninsthelper package the file OnDeletedPackage.java with the following code:
package com.example.instuninsthelper;
public interface OnDeletedPackage {
public void packageDeleted(boolean succeeded);
}
in the android.content.pm package (the namespace SHOULD not be changed) I modified the IPackageDeleteObserver.java, with this result:
package android.content.pm;
public interface IPackageDeleteObserver extends android.os.IInterface {
public abstract static class Stub extends android.os.Binder implements android.content.pm.IPackageDeleteObserver {
public Stub() {
throw new RuntimeException("Stub!");
}
public static android.content.pm.IPackageDeleteObserver asInterface(android.os.IBinder obj) {
throw new RuntimeException("Stub!");
}
public android.os.IBinder asBinder() {
throw new RuntimeException("Stub!");
}
public boolean onTransact(int code, android.os.Parcel data, android.os.Parcel reply, int flags)
throws android.os.RemoteException {
throw new RuntimeException("Stub!");
}
}
public abstract void packageDeleted(boolean succeeded)
throws android.os.RemoteException;
}
build the application in Eclipse and deploy it to the emulator
in the emulator: home button > Settings > applications > ...uninstall the application (because it is not installed in /system/app, and we just needed the generation of the apk file)
do the following to root the emulator (so that we can write in /system/app; other solution, that I have used, is to generate a custom ROM with this app included into the /system/app):
download the su file from here http://forum.xda-developers.com/showthread.php?t=682828http://forum.xda-developers.com/showthread.php?t=682828. Rename it to su.zip
then from the console:
* adb shell mount -o rw,remount -t yaffs2 /dev/block/mtdblock03 /system
* adb push su.zip /system/xbin/su
* adb shell chmod 06755 /system
* adb shell chmod 06755 /system/xbin/su
from the console, go to the /bin directory of the project, then enter:
* adb push .apk /system/app
finally, always from the console, enter:
* adb shell am start -n com.example.silentinstuninst/com.example.silentinstuninst.MainActivity
enjoy!
Don't know, but just a idea:
I think that you are writing in the standarout, not executing a command nor giving extra data to the process via its input. I think it should be:
Runtime.getRuntime().exec("pm install /mnt/sdcard/HelloAndroid.apk\n");
Hope this helps.
Installing in the /system/app directory is essentially the same as requiring root.
Assuming you have root, check out RootTools. Then you can do:
if (RootTools.isAccessGiven()) {
CommandCapture command = new CommandCapture(0, "pm install " + PATH_TO_APK);
RootTools.getShell(true).add(command).waitForFinish();
}
Note that waitForFinish() is a blocking call!
Well you can do this also with the PackageManager directly (requires root access):
Create an app with a platform-sdk which has the interfaces publicly (create or download it, and configure eclipse)
In the app directly call the hidden API functions which allow silent install/remove.
Install the APK on your device as a system app by copying it to /system/app (root needed)
See this: http://forum.xda-developers.com/showthread.php?t=1711653
Runtime.getRuntime().exec("pm install /mnt/sdcard/HelloAndroid.apk\n");
This works for me, although two more additional details have to be done:
Add android:sharedUserId="android.uid.system" in AndroidManifest.xml.
Signed the apk with the system key.
But in this way it seems there is no way to tell whether the installation is succeeded, so I will try #Ginger's method later.
For all who are still having problem: you will need a rooted device and use
Process result = Runtime.getRuntime().exec("pm install -r -d MyApp.apk /system/app")
If you are getting result code 9 (error code 9) you will need to delete your apk from the device and push it back (PUSH not INSTAL!).
Go to the device shell and Push the apk
launcher=MyApp.apk
$adb shell su -c "mount -o remount,rw -t rfs /dev/stl5 /system"
$adb push $launcher /sdcard/$launcher
$adb shell su -c "chmod 644 /system/app/$launcher"
Now you are able to use pm install without getting an error. Hope it will help somebody.
I have successfully setup the Facebook Plugin by Jos located (https://github.com/jos3000/phonegap-plugins/tree/master/Android/Facebook) - but I can't seem to figure out a way to log the user out. Sure I could tell them to delete the App access on the website then try to login again and click on "Not you?" but I would really rather have a JS Function that does it for me.
Can anyone help provide some guidance on how to do this? I've looked through the files and it looks like there is a way to do it in the facebook.java but I just need to hack something together to connect it to webview. I'm not capable of doing so :) can anyone please help?
This solution is to disable the single sign on feature in the Facebook plugin
in FaceBook.java file
replace DEFAULT_AUTH_ACTIVITY_CODE in the Authorize method [2 overloads] by FORCE_DIALOG_AUTH
in FacebookAuth.Java file
append this to execute method [in the switch case section]
else if (action.equals("performLogout")){
this.performLogout(first);}
//Add this method to FacebookAuth.java class
public void performLogout(final String appid) {
Log.d("PhoneGapLog", "LOGOUT");
final FacebookAuth fba = this;
Runnable runnable = new Runnable() {
public void run() {
fba.mFb = new Facebook(appid);
fba.mFb.setPlugin(fba);
try {
fba.mFb.logout((Activity) fba.ctx);
fba.success(new PluginResult(PluginResult.Status.OK, ""), fba.callback);
} catch (MalformedURLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
};
};
this.ctx.runOnUiThread(runnable);
}
//in facebook.js file add the following section
Facebook.prototype.Logout = function(app_id,callback){
PhoneGap.exec(callback,null, "FacebookAuth", "performLogout", [app_id]); };
// in your page add the following code
function LogoutClick() //on logout click
{
appId = "123" ; //your app Id
window.plugins.facebook.Logout(appId,CompleteLogout);
}
function CompleteLogout() //call back function
{
//do some logic for callback
}
//Enjoy..!!
