Android performance meter - android

I looking a tools that can be helps for me to measure my performance in some parts of code in my android application.
Is there any tools for help me?
Now i was written a class that measure my functions in app, but may be is exist more effective methods?

I'm not sure if you are looking for a tool to instrument your code and review your stack trace execution time or something more related to different metrics, but maybe I can help. I'm working on a tool we will release soon, this tool will allow us to monitor our application performance in production using real-time stats. The platform is named FlowUp http://flowup.io/. Just adding an Android library to your project you could monitor your application in production in real-time :)
Using FLowUp you can get information about your application performance in terms of:
Frame time.
Frames per second.
Network consumption.
CPU usage.
Disk usage.
Memory consumption in terms of load and bytes allocated.
And much more metrics. Of course, all these metrics can be reviewed crossing this information with some tags related to the application or the device. For example, you could get information about the network consumption or the frames per second of your app per activity and comparing different app or Android OS version.
This is an screenshot I've taken from our landing page:
Right now we are under development but I recommend you to subscribe to our mail list in http://flowup.io to have access to the first beta we will release soon :)
If you have any metric you'd really like to monitor, please don't hesitate to request it! Maybe we can implement this for you :)

Sure there are tools for that. Try this: Android Systrace.

Android Monitor Graph logs

I have a simple application that contains two implementations which I want to compare(benchmark) with each other in terms of usage during a certain amount of time.
The testing method is equal for both implementations (they both execute exactly the same commands/events) the only difference is the way they process the command and events.
I wish to get a log per second of:
CPU load
Memory usage
Network traffic
The Android Monitor provides everything I need in a graph and logs per second the current CPU load, Memory usage and the TX/RX for network traffic, great!
However I wish to have this all in a text log instead of a live graph. Can someone tell me where I could find such a log? OR if there is no such thing, any suggestions to get similar data?
Doppie, I looked for a solution using out-of-box tools, but there is no good way to use the Android tools to export just the information you want to a text file without lots of work. Logcat is way too verbose and requires conversion, and Dalvik doesn't exactly provide you the every-second control over data collection. I would love to have a simple solution for this too. :/
[Disclaimer: Because I work with Perfecto, I know that the devices in their cloud lab can do this easily, so if you are trying to diagnose a specific problem, you could use their free public cloud and export the device vitals (shown below). This is not a pitch, but since it's free to play, it might help you in the short-term.]
hi first of all if you looking for memory logs. There is one option you can directly go and check that one.
Open Android Device Monitor then checks heap dumps.Check the uses of memory.
Another way to monitor Android Device Monitor then see the Allocation Tracker it gives you details in everyclass where you memory is used.
Expect these things you can directly check your Current logs.
Click Android Monitor and see logcat and second option Monitors.
Monitors gives you Four type of details :
1. Memory usages.
2. CPU how kuch usages of your phone.
3. Network
4. GPU.
Now after these all things. If you still have some problem then need to check your gradle.
What kind of libraries you used.
First of all remove unwanted libraries.
Secondly need to import only useful libraries. Like if you looking for map related things in your app then import only.
compile "com.google.android.gms:play-services-maps:9.4.0"
not this one.
compile 'com.google.android.gms:play-services:9.4.0'
Aware about replication of libraries.
Example : If you using some libraries and that libaray contain appcompt and you are also using same libaray in your app side.Then its better to use that libaray as module.
At last try to use proguard rules.
These are few ways to handle better memory management.
I have made one android app architecture here is link..
Thanks hope this will help you.

Performance Testing Tools for Mobile Applications

I am testing the application on Android & iOS platforms. The application uses the device mic. Network usage is used persistent.
Can any one suggest a simple Performance Testing tool to test the following,
I need to monitor & analyse the Network Usage
I need to analyse the Battery Consumption
Need to list down the scenarios when Memory Loss occurs
Generating the reports for the above mentioned scenarios would be much appreciated.
For battery consumption monitoring on Android you can use Battery Historian.
It provides detailed information, uses JavaScript visualization libraries to display battery related events on a timeline with panning and zooming functionality
You should be using AT&Ts ARO tool for deep network usage
analysis
You should be using Battery Historian for analysis of
Battery usage
You need to leverage a set of tools to find the right Memory Loss scenarios.
Its been an old post but thought I shall mention the tools that I have been using:
mAutomate (They have been providing lots of performance graphs for memory/CPU/Network etc)
Robotium (I had to write hell lot of code for it :) & was not automated)
I have used these tools for Android Test automation. mAutomate works for iOS too ,not sure about Robotium.
You should take a look at latest native Android Studio Profiler. It contains necessary tools for your purposes and they are often upgraded. Also for working with network I would like you to recommend Charles Proxy

How can i check time taken for each screen on my android app

My PM wants me to test that how much time my android app is taking on GPRS/edge/3g when i navigate in app.
Is there any tool that i can use as he want me to use a tool that we can run.
he wants that when we use our app on mobile network how much time each page takes to load..
Please help!!
There are several tool provided by Android itself to optimize and monitor Application Performance
One of the tool is TraceView
Documentation:
Traceview is a graphical viewer for execution logs saved by your
application. Traceview can help you debug your application and profile
its performance.
Android also provides Device Monitor is available which comprises of several tools including TraceView
Documentation:
Android Device Monitor is a stand-alone tool that provides a graphical user interface for several Android application debugging and analysis tools.
Give it a try to these tools
Also if you want to find out how to improve performance, go through following blog I usually refer to optimize application performance
http://opensignal.com/blog/2013/07/30/40-developer-tips-for-android-optimization/
Hope this will help
If you are looking for a way to log the time that is spend in some method call you could use TimingLogger. With that you could log every network request and how long it takes to receive the network response.

Android - What's a good strategy to get the CPU usage of a given package?

I am trying to get the CPU usage of a given package. After some research, I found a way to get the CPU usage of a process (reading /proc/[PID]/stat/ information) but I couldn't find a way to go to the package level (a process can run many packages).
I'd say it's impossible to do given that the SDK doesn't offer such APIs to monitor CPU usage (as it does with memory usage) but I'd rather know what you think about this.
Thank you!
You actually can do this, at least using private API's. It's also not a percentage, it's instead stored as a collective "CPU time" which is used to measure power consumption. I did this a while back with a project I worked on. Check out this Google Code project. It requires using private APIs and I make no promises that those APIs still exist, but I did do it at one point.

Native Android/iOS development vs Marmalade SDK [closed]

Closed. This question needs to be more focused. It is not currently accepting answers.

Closed 7 years ago.
Improve this question
Our company is on the verge of picking between native Android/iPhone development and some cross-platform solution, specifically Marmalade SDK (former Airplay SDK).
We are a computer vision company, meaning we need low level access to the camera devices. Also, our applications are computationally expensive, meaning we tend to squeeze out every little bit of processing power available.
Our team has sufficient experience in both Objective-C and Java (or C) to provide platform specific solutions. However our main focus was always on C++, as such we would like to prevent fragmenting out team and rather work with a cross-platform solution.
Our biggest fear is that choosing Marmalade will either sacrifice processing speed (main concern) or severely increase development time by complicating low level access to camera frame buffer.
So my question is, besides the obvious, what are the advantages, but specifically limitations of Marmalade SDK for processor intensive video processing applications.
I have used Marmalade/Airplay for almost two years now in my indie game company. For me it's a win because I'm just one programmer, and I can do virtually all my work in Windows using MS Dev Studio (which is my favorite dev environment by far) and because it shields me from having to deal with a lot of the platform-specific details, especially with the various development tools, that could eat up a lot of the time I'd rather spend on game content.
Speed will not be an issue with Marmalade. Your C++ code runs natively. Also, access to camera and other functionality should not be much of an issue; it's either already provided or can be added using the extensions SDK, which is pretty straightforward to use.
Marmalade is a mature product and the company is pretty helpful in resolving issues quickly, even for indie developers that are using the product for free. In addition to the cross-platform-ness, it has some nice tools built in, such as a memory leak tracker, a logging system, graphics analysis tools, and others.
There are some downsides that I've experienced with Marmalade.
Even though in theory any API or third-party SDK is accessible through the extensions system, in practice the thing you need may not exist yet. As an example, a number of developers are currently struggling to get the analytics package Flurry integrated, and it's been a challenge for some. The situation is similar with lots of other third-party SDKs; they may be just a couple lines to integrate if you are doing Objective-C development, but can be more difficult via Marmalade.
Some things are less natural because of the cross-platform layer through which you operate. Some examples for me have been:
I've had trouble getting my splash screens (application start-up screens) to display properly in all screen sizes on both iOS and Android. And it's been hard to get them to show without some flickering, short black-out periods, or resizing of images as it transitions between the device load of the Marmalade app itself, and then Marmalade's step of loading your app code.
Marmalade imposes a very simple memory model, where you get a fixed heap up front, and all memory allocation is done through Marmalade. From the system's point of view the app just has and keeps a big block (or a few big blocks) of memory. This has some advantages, but I've had problems squaring this model with the iOS model of, for instance, receiving memory warnings and being expected to jettison any unnecessary resources. It appears to be a case where "one size fits all" ends up actually losing some key functionality.
You can use the extension manager and some other methods to show native UI elements, but integrating a significant amount of native-look-and-feel UI can be a challenge. So if your app is game-like and users can deal with non-standard buttons and so on, that's fine, but if you anticipate needing significant native UI, it is harder. [edit: Recent versions of Marmalade have added a native UI framework that lets you specify standard UI elements in a generic way and then implements then using the appropriate widgets for the device. I have not used this, but it looks fairly comprehensive.]
If you run into problems, it's often not clear whether it's a generic OS problem or a Marmalade problem, and it can be lonely trying to find help. For instance, I recently added in-app purchase to my game, on both iOS and Android. IAP is challenging, and even without an additional SDK layer there are lots of special cases to deal with. In my case, I had a situation where my app had been rejected by Apple for a small issue, and while it was in the rejected state my in-app purchase was also in a "rejected" state (even though there was nothing broken about the IAP itself; this is just a quirk of Apple's process). When I was trying to regression test the in-app purchase functionality (while I was submitting the fix for this non-in-app-purchase-related issue), the game was actually crashing, instead of getting an appropriate error result. I was able to determine that the crash wasn't in my game code, so it was either the OS (unlikely) or the Marmalade middle layer for handling the in-app purchase callbacks (which is what it turned out to be [update 11/28/2012: Marmalade has reportedly fixed this problem in a recent SDK update]).
So in a situation like that you can try going on Stack Overflow to get help, but really nobody is there to help you, so you are dependent on the Marmalade team to get back to you with an answer. As I say, they do a pretty good job of this, but there's no way it can compete with nearly instantaneous responses on Stack Overflow from the world-wide community of regular iOS programmers. So I'd say this last one is my biggest concern with using a system like Marmalade. It saves you time up front not having to come up to speed on the details of the various platform SDKs, but when you run into problems you are "at the mercy" of the Marmalade team (or friendly Marmalade community members) to get back to you with an answer. (Keep in mind here that I'm writing as a freebie indie developer who just gets standard priority for issue resolution. You can pay to get guaranteed quick resolution.) For me personally, it's been hard having to keep coming back to my producer and saying "I'm waiting for an answer from the Marmalade guys on this one."
(Another example of issue 3 is that until recently there was a problem with sound effects being delayed on certain Android devices. It was a Marmalade issue, and they did eventually resolve it, but it took a while, and there's basically nothing you can do in the meantime.)
Keep in mind that (as other responders have pointed out) even without Marmalade you can still have the bulk of your code base in C++ on either iOS or Android.
In spite of the long list of potential issues above, I am a fan of Marmalade, and I appreciate all the company has provided for me for free. The tool really shines when it comes to other platforms that you'd otherwise never bother with, such as (for me) bada or PlayBook. You really can deploy to a wide array of devices from the comfort of your PC and Developer Studio (or from a Mac with xcode, if you want to make your life a little harder ;). The simulator tool they have is great, and there have been only a small number of instances where I've had to debug on the device itself; in general if it works on the simulator it just works. IdeaWorks has taken on a huge challenge and they are doing a great job juggling all these features (i.e., basically every features ever offered on a mobile device) on all these platforms (i.e., all significant devices in existence, with the exception of Windows Phone 7 because it does not currently allow native code). It just comes with some caveats.
I am biased, being the CTO at Marmalade... but if your key requirements are (1) camera access and (2) the ability to "squeeze out every little bit of processing power available" then Marmalade is a great choice.
Marmalade compiles your C/C++ to native ARM (or x86) instructions... no transcoding, no virtual machines. It's very easy to bring across existing C/C++ code, nearly all the C/C++ standard libraries are supported, etc. And you can use ASM code within your project. Also, you can do all your development either on Windows or Mac, regardless of what platforms you deploy to (yes, you can even compile/test/deploy to iOS purely on Windws).
As far as I can tell you from ANDROID Development:
The Camera API from Android itself seems to be a little buggy (in example: before 2.1 there is no solution to get Camera shown in portrait-mode without scrambling the Images).
Another abstraction layer on top of that might be better (in terms of accessibility, features, whatever), or even more worse. What it does for shure: It steals resources, which may be needed for your own App.
Marmalade offers an excellent Native Extension framework
http://www.madewithmarmalade.com/marmalade/features/extensions-development-kit
WHich ultimately means that you can jump directly to a native implementation of any particular feature. You still keep the core benefits of cross platform development for your main app.
Also on android because marmalade makes use of the android NDK your c++ code for processing data will be running faster than the corresponding android Java code.
Im making games with Marmalade and the extensions and native code speed make me extremely confident of being able to deliver at least as well as a 'native' app.
I would use MoSync Android/iOS, but I would say that, since I work at MoSync.
But in all fairness I prefer the MoSync Camera API.
If you really want to squeeze out all the processing power out you should use ASM.

Marmalade's not bad, I used it in 2013. Some bugs, some annoyances (fixed memory pools), but overall not a bad experience.
The only real disappointment is the lack of support for Linux. I cannot see how the Marmalade guys can support obscure platforms like Blackberry, but not Linux; it makes no sense. Maybe this will change as Steam OS (a Linux-based, gaming-centric platform) matures, though admittedly Steam OS doesn't bring a whole lot to the table outside of what other OSs bring, for now.
