In this blog, i'm going to write a small code snippet that fetches some useful content from Android Phone.
Below is the snippet
1. Set up Application permissions.
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
2. Get install Application info (APK).
In your Activity/Fragment call following method that returns a list of install Application.
public List<AppInfo> getInstalledApps(Context mContext) {
List<PackageInfo> apps = mContext.getPackageManager().getInstalledPackages(0);
ArrayList<AppInfo> mInstalledApps = new ArrayList();
for (PackageInfo p : apps) {
if (!isSystemPackage(p)) {
AppInfo newInfo = new AppInfo();
newInfo.setAppName(p.applicationInfo.loadLabel(mContext.getPackageManager()).toString());
newInfo.setPackageName(p.packageName);
newInfo.setAapVersion(p.versionName);
newInfo.setAppVersionCode(p.versionCode);
newInfo.setAppAPKUrl(p.applicationInfo.publicSourceDir);
newInfo.setAppIcon(p.applicationInfo.loadIcon(mContext.getPackageManager()));
mInstalledApps.add(newInfo);
}
}
}
return mInstalledApps;
}
private boolean isSystemPackage(PackageInfo packageInfo) {
return (packageInfo.applicationInfo.flags & ApplicationInfo.FLAG_SYSTEM) != 0;
}
2. Get Video.
In this snippet, We fetch all video in Android Phone.
public List<MediaModel> getVideos(Context mContext){
ArrayList<MediaModel> mVideos = new ArrayList<>();
String[] videoProjection = {MediaStore.Video.Media._ID,
MediaStore.Video.Media.DATA,
MediaStore.Video.Media.DISPLAY_NAME,
MediaStore.Video.Media.SIZE,
MediaStore.Video.Media.SIZE};
makeList(mContext.getContentResolver().query(MediaStore.Video.Media.EXTERNAL_CONTENT_URI, videoProjection, null, null, null), mVideos);
return mVideos;
}
3. Get Audio.
In this snippet, We fetch mp3 and wav Audio files from Android Phone.
public List<MediaModel> getAudios(Context mContext) {
ArrayList<MediaModel> mAudios = new ArrayList<>();
String[] videoProjection = {MediaStore.Audio.Media._ID,
MediaStore.Audio.Media.DATA,
MediaStore.Audio.Media.DISPLAY_NAME,
MediaStore.Audio.Media.SIZE, MediaStore.Audio.Media.ALBUM_ID};
makeList(mContext.getContentResolver().query(MediaStore.Audio.Media.EXTERNAL_CONTENT_URI, videoProjection,
MediaStore.Files.FileColumns.MIME_TYPE + "=?",
new String[]{MimeTypeMap.getSingleton().getMimeTypeFromExtension(mContext.getResources().getString(R.string.wav))}, null), mAudios);
makeList(mContext.getContentResolver().query(MediaStore.Audio.Media.EXTERNAL_CONTENT_URI, videoProjection, MediaStore.Files.FileColumns.MIME_TYPE + "=?",
new String[]{MimeTypeMap.getSingleton().getMimeTypeFromExtension(mContext.getResources().getString(R.string.mp3))}, null), mAudios);
return mAudios;
}
4. Get Image.
In this snippet, We fetch all images from Android Phone.
public List<MediaModel> getImages() {
if (mImages == null || mImages.isEmpty()) {
mImages = new ArrayList<>();
String[] videoProjection = {MediaStore.Images.Media._ID,
MediaStore.Images.Media.DATA,
MediaStore.Images.Media.DISPLAY_NAME,
MediaStore.Images.Media.SIZE,
MediaStore.Images.Media.SIZE};
makeList(mContext.getContentResolver().query(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, videoProjection, null, null, null), mImages);
}
return mImages;
}
5. Text Files.
In this snippet, We fetch only PDF files from Android Phone. You can get all files by changes just extension in below snippet.
public List<MediaModel> getFiles() {
if (mFiles == null || mFiles.isEmpty()) {
mFiles = new ArrayList();
String[] videoProjection = {MediaStore.Files.FileColumns._ID,
MediaStore.Files.FileColumns.DATA,
MediaStore.Files.FileColumns.DISPLAY_NAME,
MediaStore.Files.FileColumns.SIZE};
makeList(mContext.getContentResolver().query(MediaStore.Files.getContentUri(mContext.getResources().getString(R.string.external)), videoProjection, MediaStore.Files.FileColumns.MIME_TYPE + "=?",
new String[]{MimeTypeMap.getSingleton().getMimeTypeFromExtension("
pdf")}, null), mFiles);
return mFiles;
}
Method and Model classes that are used in the above snippets.
A). makeList(@NonNull Cursor audioFilesCursor, ArrayList<MediaModel> arrayList)
private void makeList(@NonNull Cursor audioFilesCursor, ArrayList<MediaModel> arrayList) {
audioFilesCursor.moveToFirst();
while (!audioFilesCursor.isAfterLast()) {
MediaModel mediaModel = new MediaModel(audioFilesCursor.getString(1), new File(audioFilesCursor.getString(1)).getName());
if (mHomeContract.isSelected(audioFilesCursor.getString(1))) {
mediaModel.setIsSelected(true);
}
arrayList.add(mediaModel);
audioFilesCursor.moveToNext();
}
audioFilesCursor.close();
}
B). MediaModel
public class MediaModel {
private String url;
private String name;
private boolean isSelected;
/**
* Instantiates a new Audio model.
*
* @param fileUrl the audio url
* @param fileName the audio name
*/
public MediaModel(String fileUrl, String fileName) {
url = fileUrl;
name = fileName;
}
/**
* Gets url.
*
* @return the url
*/
public String getUrl() {
return url;
}
/**
* Gets name.
*
* @return the name
*/
public String getName() {
return name;
}
/**
* Is selected boolean.
*
* @return the boolean
*/
public boolean isSelected() {
return isSelected;
}
/**
* Sets is selected.
*
* @param isSelected the is selected
*/
public void setIsSelected(boolean isSelected) {
this.isSelected = isSelected;
}
}
C). Create a model that keep information of install Application in your device.
public class AppInfo {
private String appAPKUrl;
private String appName;
private String appPackage;
private String aapVersion;
private int appVersionCode;
private Drawable appIcon;
private boolean isSelected;
public String getAppAPKUrl() {
return appAPKUrl;
}
public String getAppName() {
return appName;
}
public String getPackageName() {
return appPackage;
}
public String getAapVersion() {
return aapVersion;
}
public int getAppVersionCode() {
return appVersionCode;
}
public Drawable getAppIcon() {
return appIcon;
}
public boolean isSelected() {
return isSelected;
}
public void setIsSelected(boolean isSelected) {
this.isSelected = isSelected;
}
public void setAppAPKUrl(String appAPKUrl) {
this.appAPKUrl = appAPKUrl;
}
public void setAppName(String appName) {
this.appName = appName;
}
public void setPackageName(String packageName) {
this.appPackage = packageName;
}
public void setAapVersion(String aapVersion) {
this.aapVersion = aapVersion;
}
public void setAppVersionCode(int appVersionCode) {
this.appVersionCode = appVersionCode;
}
public void setAppIcon(Drawable appIcon) {
this.appIcon = appIcon;
}
}
