+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its

+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.

+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.

+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+## Using PRDownloader Library in your Android application
+
+Add this in your `settings.gradle`:
+```groovy
+maven { url 'https://jitpack.io' }
+```
+
+If you are using `settings.gradle.kts`, add the following:
+```kotlin
+maven { setUrl("https://jitpack.io") }
+```
+
+Add this in your `build.gradle`
+```groovy
+implementation 'com.github.amitshekhariitbhu:PRDownloader:1.0.2'
+```
+
+If you are using `build.gradle.kts`, add the following:
+```kotlin
+implementation("com.github.amitshekhariitbhu:PRDownloader:1.0.2")
+```
+
+Do not forget to add internet permission in manifest if already not present
+```xml
+<uses-permission android:name="android.permission.INTERNET" />
+```
+Then initialize it in onCreate() Method of application class :
+```java
+PRDownloader.initialize(getApplicationContext());
+```
+Initializing it with some customization
+```java
+// Enabling database for resume support even after the application is killed:
+PRDownloaderConfig config = PRDownloaderConfig.newBuilder()
+                .setDatabaseEnabled(true)
+                .build();
+PRDownloader.initialize(getApplicationContext(), config);
+
+// Setting timeout globally for the download network requests:
+PRDownloaderConfig config = PRDownloaderConfig.newBuilder()
+                .setReadTimeout(30_000)
+                .setConnectTimeout(30_000)
+                .build();
+PRDownloader.initialize(getApplicationContext(), config); 
+```
+
+### Make a download request
+```java
+int downloadId = PRDownloader.download(url, dirPath, fileName)
+                        .build()
+                        .setOnStartOrResumeListener(new OnStartOrResumeListener() {
+                            @Override

+                               
+                            }
+                        })
+                        .setOnPauseListener(new OnPauseListener() {
+                            @Override

+                               
+                            }
+                        })
+                        .setOnCancelListener(new OnCancelListener() {

+                            }
+                        })
+                        .setOnProgressListener(new OnProgressListener() {
+                            @Override
+                            public void onProgress(Progress progress) {

+                        })
+                        .start(new OnDownloadListener() {

+                            }
+
+                            @Override

+                            }
+                        });            
+```
+
+### Pause a download request
+```java
+PRDownloader.pause(downloadId);
+```
+
+### Resume a download request
+```java
+PRDownloader.resume(downloadId);
+```
+
+### Cancel a download request
+```java
+// Cancel with the download id
+PRDownloader.cancel(downloadId);
+// The tag can be set to any request and then can be used to cancel the request
+PRDownloader.cancel(TAG);
+// Cancel all the requests
+PRDownloader.cancelAll();
+```
+
+### Status of a download request
+```java
+Status status = PRDownloader.getStatus(downloadId);
+```
+
+### Clean up resumed files if database enabled
+```java
+// Method to clean up temporary resumed files which is older than the given day
+PRDownloader.cleanUp(days);
+```
+### TODO
+* Integration with other libraries like OkHttp, RxJava
+* Test Cases
+* And of course many many features and bug fixes
+
+## [Outcome School Blog](https://outcomeschool.com/blog) - High-quality content to learn Android concepts.

+#   Gradle start up script for POSIX generated by Gradle.
+#
+#   Important for running:
+#
+#   (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
+#       noncompliant, but you have some other compliant shell such as ksh or
+#       bash, then to run this script, type that shell name before the whole
+#       command line, like:
+#
+#           ksh Gradle
+#
+#       Busybox and similar reduced shells will NOT work, because this script
+#       requires all of these POSIX shell features:
+#         * functions;
+#         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
+#           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
+#         * compound commands having a testable exit status, especially «case»;
+#         * various built-in commands including «command», «set», and «ulimit».
+#
+#   Important for patching:
+#
+#   (2) This script targets any POSIX shell, so it avoids extensions provided
+#       by Bash, Ksh, etc; in particular arrays are avoided.
+#
+#       The "traditional" practice of packing multiple parameters into a
+#       space-separated string is a well documented source of bugs and security
+#       problems, so this is (mostly) avoided, by progressively accumulating
+#       options in "$@", and eventually passing that to Java.
+#
+#       Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
+#       and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
+#       see the in-line comments for details.
+#
+#       There are tweaks for specific operating systems such as AIX, CygWin,
+#       Darwin, MinGW, and NonStop.
+#
+#   (3) This script is generated from the Groovy template
+#       https://github.com/gradle/gradle/blob/HEAD/platforms/jvm/plugins-application/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
+#       within the Gradle project.
