Motorola Droid :: Browser Scroll Lag?
Jan 5, 2010
I finally got fed up today with the phone being laggier than ever before. i dunno what was wrong. i wasn't using any home app. no streaming widgets on the home screen. no gps on, no wifi. no cpu intensive apps running in the background. nothing i had should really be lagging the phone in any way. but it would still get laggy for no reason sometimes. and it happens randomly. scrolling through menus. lag. swiping through screens. lag. pressing drawer tab. lag. scrolling through apps. lag. and its random. sometimes its smooth but other times its just incredibly frustrating. it gets to the point where i think the phone just crashed.
So i figured it must be these apps i installed. but they weren't even running in the background so it made no sense. but i decided to uninstall them anyway. i decided to just uninstall all the games and apps that i dont play or use. ended up uninstalling about 15 dif things. can't remember specific ones. but after i did the uninstalls, i scrolled/swiped around and it seemed to be much smoother!! checked the browser and engadget and this site seemed to scroll much smoother. so i restarted my phone to really clean it all out just in case, and it really does seem like the browser lag was gone!
I used the built in android uninstaller in the applications menu to uninstall. uninstalled a bunch of sound boards and free games. not sure what app was the culprit. but i do remember having some locale sync plugin still installed even though i didnt have locale installed anymore. also uninstalled some kinda OI plugin? a plugin for OI? i also uninstalled Hi AIM. these seemed to be the most significant ones to me and what i saw as the most likely culprits. wish i had documented all my steps now because this has definitely fixed the lag problem for me. screens swipe super smooth now, menus scroll with no hiccups. browser scrolling speed is back to the way it was before 2.0.1.

I am trying to pull up a page that is a search screen. My friends can pull up on iphone but I have tried multiple browsers on my Droid X and it won't let me scroll to the bottom of the page, which is where you would enter a search. the page is Browse View Frame page. I have tried the stock browser and Dolphin.

I just wanted to test how to move on a touchscreen the slider of a scroll bar, but big surprise, there is no scroll bar. I have defined a DIV with overflow:auto This means when the content of the DIV is greater than the DIV defined with style width and height, there should be scroll bars added to the DIV. But at this test page the left menu is larger than the DIV, but no scroll bar is added to the DIV. When you test it with an Android cell phone, You will have first scroll the screen to the left.

Did anybody found out (if it is even possible) how to scroll iframe in Android's browser?
For those that do not know what iFrame it is basically a frame inside a normal HTML document - please check this for the example - http://www.htmlcodetutorial.com/frames/_IFRAME_SCROLLING.html
On the iPhone you scroll iframe inside the page by putting 2 fingers on the frame (instead of usual one for scrolling).
I have some web pages that use iframe and it is very frustrating not to be able to use them on my phone.

On the iPhone, safari strips out scrollbars on divs that have overflow set to auto or scroll, but still lets the user scroll with the two-finger swipe gesture.
Using an HTC Incredible, we see the scrollbars are again missing, but we cannot figure out any gesture that allows the user to scroll. Is there a special directive we need to add to our HTML? This should affect zillions of websites, any time someone is trying to scroll an area of the page rather than the whole page. Does anyone know how to enable scrolling a div using the web browser on Android phones?

I'm starting to use a web interface (java from what I can tell) to stream my tv to my phone. Everything works great, except the channel list is it's own frame, and I cant scroll it. I can only see the first 15 out of 100 channels. I've searched google and cant find any information about this. I've also tried Skyfire and Dolphin, but with no luck. Does anyone know a workaround to scroll within a frame? The iphone and ipad can scroll within a frame by using two fingers in stead of one. There must be a workaround for android.

Maybe its just me but with this RUU and full flash, the browser scrolls a lot slower. I was running skyraider before and noticed this after I installed the full flash apk. Removed full flash and scrolling sped up like before.
Anyone notice this?
I'm temped to revert back to either skyraider or flash lite. The browser lag is quite annoying. Anyone know how to disable full flash in the latest leak (cant uninstall it). I imagine i could just rename something. Any tips?

I came to the Hero from the iPhone where there was a way to quickly scroll back up to the top of a webpage by clicking on the top of the address bar - in the included browser on the hero if I read a long vertical site I have to scroll and scroll and scroll and scroll some more to get back to the top - am I missing something or is this really the only way to do this?

So everything is perfect about my Eris except that the scroll-ball doesn't scroll left anymore. This isn't the first time the problem came up. My last Eris had the same problem. It scrolls in every direction except which is kinda annoying as I use it alot more than I thought I would. Should I take it up with Verizon? It isn't a life or death situation but it makes editing sentences in texts a pain.

Here's a general question... I have an evo and there are apps like the htc gallery where smoothness of the animation are just as good as the iphones.
But why doesn't the browser zoom and scroll as nice as the iphone browser? Don't we have enough horsepower to match the quality as the iphone rendering?

I have a Motorola droid (orig) that when you are web browsing there is a bar that comes up on the bottom right with +/- to adjust zoom level. Does this still exist on the Droid 2 Stock Browser?

When you are reading an email, is there a way to swype to move to the next email? Coming from a Storm, a finger swipe left or right advanced you to the adjacent email. On the X, AFAIK, you have to back out to the list of emails and highlight the next one to read.

Does anyone's app screen stutter slightly when scrolling? If you quick flick to the bottom it seems somewhat ok but if you slow-scroll it seems to stutter. It just isn't as smooth as my iPhone. It's not terrible but comparatively annoying.

I assume that I am not the only Droid's owner who has this weird experience with the device: sometimes when I touch on a list (e.g., Apps listed on Market) or a web-page. The list or page will rapidly scroll all the way to the bottom of the list or page. Although I experience this at least a couple times every day, I am unable to reproduce this phenomenon at will.Does anyone know what cause this? Is it a bug?

I've got this odd problem which is happening on 1.6, 2.2, and a MyTouch 3G Slide (which is API #7, and listed as "2.1-Update1" in the Android Device Chooser). If anyone can explain what I'm doing wrong & how to fix it (or possibly confirm that this is an Android bug)The basic idea for my app is to make a stopwatch-sort of thing, in that the user can tap a button to start a timer, then tap it again to stop (pause) the timer; further taps alternate between resuming the timer and pausing the timer.I've got a top-level ScrollView which contains a RelativelLayout, which contains a bunch of widgets. The first widget is a HUGE button (so that it's easy to press), which pushes all my other widgets below the bottom of the screen. This is intentional, as I want to rely on the ScrollView (and an on-screen reminder to the user) to make the rest of the input options available.I've got a simple state-machine type setup, where mState is the current mode (STATE_ TIMER_ NOT_ STARTED before the user presses any buttons, RUNNING after the first press, and then PAUSED after the second, back to RUNNING after the third, etc, etc).
All this works great EXCEPT that when the timer is running, and the user presses the start/stop/resume button again, the ScrollView will scroll down a ways. I am NOT issuing this command (I don't even have a reference to ScrollView object), and I'm not sure why it's doing this.
REPRO:Compile + run the below samples. When the app starts, press the 'Start Timing' button. Use your thumb (or the mouse) to touch-drag the screen upwards (so you can see the RatingBar), then drag it back downwards (so the button is again completely on-screen). Tap the button (which now reads 'PauseTiming') again, and it'll jump down a bit. It should NOT be jumping/scrolling down, since there's no statement (that I can see) that tells it to scroll down. As near as I can tell, it's the setText that causes the scrolling ( when I comment those lines out, no scrolling occurs).WHAT I'M ASKING FOR:if I'm doing something dumb & you could point out what it is, I'd really appreciate it! I wonder if 'touch mode' might have something to do with this, since it does NOT appear to happen (in the emulator) when I use the mouse's scroll wheel to move the panel upwards (i.e.,instead of the simulated finger-dragging). I can't find a whole lot on touch-mode, and nothing specific on focus/selection in touch mode within a ScrollView if you can confirm that this error occurs for you too, that would be ok, too (since misery loves company.AHEM I mean, since it might help confirm that it's not just me MyTestApp.java package bug.android.scrollview;

UPDATE 1: Adding if( btnStartStopResume.isInTouchMode() )
Toast.makeText(this, "TOUCH MODE", 2000);
elseToast.makeText(this, "NOT touch mode", 2000);
then setting breakpoints in the debugger confirms that the button is always in touch mode (regardless of whether I finger-drag the panel up/down, or mouse-wheel it up/down). So it's a combination of being in touch-mode AND finger-dragging the panel after the 2nd button-press (i.e, when the app is in 'stopped/paused timing' mode) that's causing the odd extra-timing in subsequent pauses.
UPDATE 2:
I just noticed that it's scrolling down to the EditText, and no further. It looks like when you move the panel down the EditText gets the selection, and after the click event the ScrollView scrolls back to the thing that has the selection. Seems to explain why the mouse-wheel approach doesn't have this problem (it moves the selection/focus back up to the button).

I want to have a dynamic table, with rows added over time as a result of user interaction, using a TableLayout inside a ScrollView. This works fine, but when I want to scroll to the end of the table using fullScroll(), it always leaves out the last line; that is, it scrolls so that the one before the last one is visible. The last line is visible when scrolling manually, and the scrollbar is correct too.I'm of course open to suggestions as to how to make a better layout out of this; but I'm specifically interested in understanding why fullScroll() behaves that way. Should I give it a different parameter, or use something else altogether? Or does it do that because the newly added line isn't yet visible somehow? (if so, how can I solve that?) Or did I miss some other obvious thing?The following code replicates the problem: TestActivity.java:
package com.example.android.tests;
import java.util.Random;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.ScrollView;
import android.widget.TableLayout;
import android.widget.TableRow;
import android.widget.TextView;
public class TestActivity extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
((Button) findViewById(R.id.AddRow)).setOnClickListener(new View.OnClickListener() { public void onClick(View v) {
Random rnd = new Random();
TableRow nr = new TableRow(v.getContext());
for (int c=0; c<3; c++) {
TextView nv = new TextView(v.getContext());
nv.setText(Integer.toString(rnd.nextInt(20)-10));
nr.addView(nv);
}((TableLayout) findViewById(R.id.Table)).addView(nr);
// Scrolls to line before last - why?
((ScrollView) findViewById(R.id.TableScroller)).fullScroll(View.FOCUS_DOWN);
}main.xml:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<Button
android:text="Add Row"
android:id="@+id/AddRow"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true" />
<ScrollView
android:id="@+id/TableScroller"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_above="@id/AddRow"
android:layout_alignParentTop="true" >
<TableLayout
android:id="@+id/Table"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:stretchColumns="0,1,2" />
</ScrollView>
</RelativeLayout>
Edit: for reference, I implemented Romain Guy's solution as follows:In TestActivity.java, replace:
// Scrolls to line before last - why?
((ScrollView) findViewById(R.id.TableScroller)).fullScroll(View.FOCUS_DOWN);
// Enqueue the scrolling to happen after the new row has been layout
((ScrollView) findViewById(R.id.TableScroller)).post(new Runnable() {
public void run() {
((ScrollView) findViewById(R.id.TableScroller)).fullScroll(View.FOCUS_DOWN);

is there no way to change the timeout to scroll in ScrollView? In the source, it's set to: static final int ANIMATED_SCROLL_GAP = 250; so any drags will be blocked for 250ms. This has the appearance of the ScrollView being stuck for a bit before it moves. This makes small scroll gestures difficult to work with. There's no way around this?

I have installed Dolphin and like it, and I've made it my default browser, which is great. However, it is not only the system default, but it even opens links I click on in the Android provided browser (sometimes I both open). On your computer, when you click links in your non-default browser it doesn't send the links to the default one, and it shouldn't on this OS, either. Any ideas how to keep Dolphin as my system default browser, but not have it open links I click on in the Android web browser?

I was wondering, all my school networks have you log on once you get in the browser to show you a valid user. However, even though I have WiFi on and I am connected to the network, if I go into the browser it clearly just uses the signal I have for cell, not WiFi. I'd like to have the faster connection, but I feel like you have to be on only WiFi in order to put in that information, but I couldn't turn off my wireless network. Is there a way to do this, or is there a way to make this log in thing much easier? Cause I don't really want to turn my wireless cell connection on off everytime I want to authenticate ya know?

How are you supposed to shut down the browser? On most applications you either have an exit button, or you need to back out of it, but with the browser, when you back ut, you have to back out through all the webpages you've been looking at with it. Or am I missing a close shortcut?
