android - By running the App on versions below 22 Changes some views? -

-

i developing app minsdkversion 11, targetsdkversion 23 , compile/build tool version 23. on android versions, 5 , 6 app works fine, installing app on versions below 22 modifies layouts, buttons , text fields disappear or color changes, me this.

manifest file

<manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.khan.bilal.salamrides2">  <application android:allowbackup="true" android:icon="@mipmap/cc" android:label="@string/app_name" android:supportsrtl="true" android:theme="@style/apptheme">

styles file

<resources>      <!-- base application theme. -->     <style name="apptheme" parent="theme.appcompat.light.noactionbar">         <!-- customize theme here. -->         <item name="android:windownotitle">true</item>         <item name="colorprimary">@color/colorprimary</item>         <item name="colorprimarydark">@color/colorprimarydark</item>         <item name="coloraccent">@color/coloraccent</item>     </style>      <style name="apptheme.appbaroverlay"              parent="themeoverlay.appcompat.dark.actionbar" />      <style name="apptheme.popupoverlay"                             parent="themeoverlay.appcompat.light" />  </resources>

build gradle

apply plugin: 'com.android.application'  android {     compilesdkversion 23     buildtoolsversion "23.0.1"      defaultconfig {         applicationid "com.khan.bilal.salamrides2"         minsdkversion 11         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:design:23.4.0'     compile 'com.android.support:support-v4:23.4.0' }

screen shot of android version 22(works fine) working fine

screen shot of android version below 22(problem occurs) enter image description here

when use element introduced in api 21, , try show on phone api 11, there surely problem. older versions, have differentiate between elements showing - if element not meant used in api lower 21, have provide if-else check , if api lower 21, use simple element sure supported in api 11.

for example, if want use textinputlayout, surely can, library supports api 22+, lower versions should input text adding classic edittext. add both of them xml, hide them, , based on user's api show 1 or other.

also, read document. https://developer.android.com/training/basics/supporting-devices/platforms.html

especially should idea , how it:

private void setupactionbar() { // make sure we're running on honeycomb or higher use actionbar apis if (build.version.sdk_int >= build.version_codes.honeycomb) {     actionbar actionbar = getactionbar();     actionbar.setdisplayhomeasupenabled(true);     } }

good luck :)

Android volley - avoid multiple requests of the same kind to the server? -

-
i using volley upload list of images server. happens within service. once image uploaded remove list. problem arises when internet connection breaks. when internet connection breaks , comes again thinking of adding images yet uploaded request queue. this can result in more 1 copy of same image saved on server request same image might have gone through before getting rseponse. how can address scenario? i'm not quite sure why you're using service schedule requests volley automatically runs it's request in seperate thread. nevertheless can listen both request results, successful , unsuccessful adding listeners. you can remove image list schedule request using volley. if succeeds can carry on desired, if fails can add again list. public static request getimageuploadrequest(final string image) { response.listener<t> responselistener = new response.listener<t>() { @override public void onresponse(t response
