Re: [android-developers] where am I wrong?

[sardar khan]

what error you are getting the code seems to be fine but call the invia
method from oncreate and why you pass view as method argument.

[android-developers] Just a simple settings App

[Camille Block]

Hi everyone,

   I am looking to build a very simple settings app, with 3 'pages' (ie 
Settings 1, Settings 2, Settings 3) that connects to mysql. I do not know 
Java, and am kicking myself trying to figure out even the most simple 
items! Does anyone know of a simple interface that I can use, or a project 
template that I can just edit the fields for? Any help would be extremely 
appreciated! Cheers,

- Camille

[android-developers] Intent any type confusion from Send Binary Content of android docs

[keithlanding1992]

I found a note in the Send Binary Content 
,says:
 
**You can use a MIME type of "\*/*", but this will only match activities 
that are able to handle generic data streams.** 

Does this means i will get less match result if I use \*/* instead of a 
specific one like text/plain ? But I have write codes which turns out not. 
here is my code:

private void textIntent() {
Intent sendIntent = new Intent();
sendIntent.setAction(Intent.ACTION_SEND);
sendIntent.setType("*/*");
// sendIntent.setType("text/plain");
Uri uriToImage = 
Uri.parse("https://developer.android.com/training/sharing/send.html;);
sendIntent.putExtra(Intent.EXTRA_STREAM, uriToImage);

PackageManager packageManager = getPackageManager();
List activities = 
packageManager.queryIntentActivities(sendIntent,
PackageManager.GET_RESOLVED_FILTER);
Log.i("Log", "size: " + activities.size());
for (ResolveInfo info : activities) {
Log.i("Log", "info: " + info.toString());
IntentFilter filter = info.filter;
if (filter == null) {
Log.i("Log", "filter is null");
continue;
}
printIterator("action", filter.actionsIterator());
printIterator("category", filter.categoriesIterator());
printIterator("type", filter.typesIterator());
printIterator("schemes", filter.schemesIterator());
}

Intent chooser = Intent.createChooser(sendIntent, "title");
startActivity(chooser);
}

private void printIterator(String type, Iterator it) {
if (it == null) {
Log.i("Log", "no " + type);
return;
}
while (it.hasNext()) {
Log.i("Log", type + " : " + it.next());
}
}

So my question is :  What does  **You can use a MIME type of "\*/*", but 
this will only match activities that are able to handle generic data 
streams.**  means ?

[android-developers] Re: Zipalign does not work!

[Jim Roal]

I have battled this too.  I get random zipalign errors.  Clean and rebuild 
and get different errors.  The sometimes I can get it zipaligned, go to 
upload the Play Store, now I get signing errors.  I know the signed app 
works because I sideloaded it over a previous signed installation with no 
issues.  I play around with small source edits, rerun everything, and once 
in a while one will actually upload OK.  I have to manually zipalign every 
time though.  What is up with this?

I am making a captive portal for Android:

   1. the user connect to Wi-Fi
   2. the captive portal open with informations for login (302 of 
   /generate_204)
   3. I post the informations and release the user to use internet (204 of 
   /generate_204)
   4. *THE PROBLEM:* the captive portal close and the browser not open

My purpose is - after the post the informations - release the user, close 
captive portal and open the browser.

How I do this?

[android-developers] Android Studio memory monitor shows memory increasing for no obvious reason

[Momchil Ivanov]

I was profiling the memory of my Android app via the Android Studio memory 
monitor (no crashes, just checking) and noticed that it keeps growing until 
about 25MB until GC collection reduces it to 16MB, and then the same things 
happens again and again (see image link below).

I decided to remove absolutely all method calls, and leave out the main 
activity (the one and only of my app) completely empty (i.e. onPause, 
onResume have no logic at all), and my app is just a blank white screen, 
and yet I am seeing this heap memory constant growth for some weird reason. 
Does anybody have an idea what's going on, or how can I further investigate 
this?

Android memory usage 


As I mentioned above, I have cleared everything, deleted all files and 
resources I had. Currently my app looks like this:

build.gradle:

apply plugin: 'com.android.application'

android {
compileSdkVersion 23
buildToolsVersion "23.0.2"

defaultConfig {
applicationId "com.wow.memorytest"
minSdkVersion 16
targetSdkVersion 23
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 
'proguard-rules.pro'
}
}
}

dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:23.4.0'
compile 'com.android.support:support-v4:23.4.0'
}

My AndroidManifest.xml:


http://schemas.android.com/apk/res/android;
package="com.wow.memorytest">












MainActivity.java

package com.wow.memorytest;


import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;


public class MainActivity extends AppCompatActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main_activity);
}
}


And this still produces those constant allocation at about every 5 seconds. 
I have no idea how to further investigate this, I quickly compared two heap 
dumps but, I don't really see any obvious problem. Please let me know if 
you could help, or you'd need more information to help answer this question.


Thanks a lot,

Momchil

[android-developers] Re: Give a review as a beta tester on production version

[Forky]

Hey Mathias,

I'm seeing the same error. Did you hear back from google regarding this at 
all? Or did you just have to remove all your testers from your beta list in 
order to allow them to write reviews?

Thanks,

Chris

[android-developers] "Your SDK location contains non-ASCII characters"

[260]

Any way to go around that? And I don't mean by changing the location where 
I keep the SDK (too many changes to the toolchain), or by keeping two 
separate copies of the SDK.
The SDK is in default location (windows 7, %LOCALAPPDATA%/Android/sdk), but 
my windows user name contains non-ascii characters.

For now I might just keep using eclipse, but google says:

"*The Eclipse ADT plugin is no longer supported per our announcement 
.*
 Android 
Studio  is now the 
official IDE for Android, so you should migrate your projects to Android 
Studio as soon as possible. For more information on transitioning to 
Android Studio, see Migrate to Android Studio from Eclipse 
."
