Some Incompatible API Usages in APP

For your app, we have found that this project has accessed the following APIs which are available only on an API level higher than the declared minSdkVersion and which are accessed without proper protection. In other words, if those APIs get called at runtime, it will trigger a NoSuchMethodError and thus result in a crash of the running application.

1. <android.content.Context: int getColor(int)>: [23,30]

Error path: <com.amaze.filemanager.asynchronous.services.ZipService: void <init>()>[[]]--><com.amaze.filemanager.asynchronous.services.AbstractProgressiveService: void <init>()>[[]]--><android.content.Context: void <init>()>[]--><android.content.Context: int getColor(int)>

Error path: <com.amaze.filemanager.asynchronous.services.EncryptService: void <init>()>[[]]--><com.amaze.filemanager.asynchronous.services.AbstractProgressiveService: void <init>()>[[]]--><android.content.Context: void <init>()>[]--><android.content.Context: int getColor(int)>

You can add an if-then check like "If(Build.VERSION.SDK_INT >= 23)" when invoking this API to prevent compatibility issues.

2. <android.security.keystore.KeyGenParameterSpec.Builder: android.security.keystore.KeyGenParameterSpec.Builder setBlockModes(java.lang.String[])>: [23,30]

Error path: <com.amaze.filemanager.asynchronous.services.EncryptService$BackgroundTask: java.lang.Void doInBackground(java.lang.Void[])>[[]]--><com.amaze.filemanager.filesystem.files.CryptUtil: void <init>(android.content.Context,com.amaze.filemanager.filesystem.HybridFileParcelable,com.amaze.filemanager.utils.ProgressHandler,java.util.ArrayList,java.lang.String)>[]--><com.amaze.filemanager.filesystem.files.CryptUtil: void aesDecrypt(java.io.BufferedInputStream,java.io.BufferedOutputStream)>[[]]--><com.amaze.filemanager.filesystem.files.CryptUtil: java.security.Key getSecretKey()>[[]]--><android.security.keystore.KeyGenParameterSpec.Builder: void <init>(java.lang.String,int)>[]--><android.security.keystore.KeyGenParameterSpec.Builder: android.security.keystore.KeyGenParameterSpec.Builder setBlockModes(java.lang.String[])>

You can add an if-then check like "If(Build.VERSION.SDK_INT >= 23)" when invoking this API to prevent compatibility issues.

3.<android.view.View: void setBackgroundTintList(android.content.res.ColorStateList)>:[21,30]

Error path: <com.amaze.filemanager.ui.activities.MainActivity: void onActivityResult(int,int,android.content.Intent)>[[]]--><com.amaze.filemanager.ui.views.drawer.Drawer: void onActivityResult(int,int,android.content.Intent)>[[$i0 >= 19]]--><com.amaze.filemanager.ui.views.drawer.Drawer: void setDrawerHeaderBackground()>[[]]--><android.view.View: void <init>(android.content.Context)>[]--><android.view.View: void setBackgroundTintList(android.content.res.ColorStateList)>

You can add an if-then check like "If(Build.VERSION.SDK_INT >= 21)" when invoking this API to prevent compatibility issues.

3.<android.content.Context: java.io.File[] getExternalFilesDirs(java.lang.String)>:[19,30]

Error path: <com.amaze.filemanager.asynchronous.services.ZipService: void <init>()>[[]]--><com.amaze.filemanager.asynchronous.services.AbstractProgressiveService: void <init>()>[[]]--><android.content.Context: void <init>()>[]--><android.content.Context: java.io.File[] getExternalFilesDirs(java.lang.String)>
Error path: <com.amaze.filemanager.asynchronous.services.CopyService: void <init>()>[[]]--><com.amaze.filemanager.asynchronous.services.AbstractProgressiveService: void <init>()>[[]]--><android.content.Context: void <init>()>[]--><android.content.Context: java.io.File[] getExternalFilesDirs(java.lang.String)>

You can add an if-then check like "If(Build.VERSION.SDK_INT >= 19)" when invoking this API to prevent compatibility issues.

4.<javax.crypto.spec.GCMParameterSpec: void (int,byte[])>:[19,30]

Error path: <com.amaze.filemanager.asynchronous.services.EncryptService$BackgroundTask: java.lang.Void doInBackground(java.lang.Void[])>[[]]--><com.amaze.filemanager.filesystem.files.CryptUtil: void <init>(android.content.Context,com.amaze.filemanager.filesystem.HybridFileParcelable,com.amaze.filemanager.utils.ProgressHandler,java.util.ArrayList,java.lang.String)>[]--><com.amaze.filemanager.filesystem.files.CryptUtil: void aesDecrypt(java.io.BufferedInputStream,java.io.BufferedOutputStream)>[[]]--><javax.crypto.spec.GCMParameterSpec: void <init>(int,byte[])>

You can add an if-then check like "If(Build.VERSION.SDK_INT >= 19)" when invoking this API to prevent compatibility issues.

5.<android.security.keystore.KeyGenParameterSpec.Builder: android.security.keystore.KeyGenParameterSpec.Builder setRandomizedEncryptionRequired(boolean)>
:[23,30]

Error path: <com.amaze.filemanager.asynchronous.services.EncryptService$BackgroundTask: java.lang.Void doInBackground(java.lang.Void[])>[[]]--><com.amaze.filemanager.filesystem.files.CryptUtil: void <init>(android.content.Context,com.amaze.filemanager.filesystem.HybridFileParcelable,com.amaze.filemanager.utils.ProgressHandler,java.util.ArrayList,java.lang.String)>[]--><com.amaze.filemanager.filesystem.files.CryptUtil: void aesDecrypt(java.io.BufferedInputStream,java.io.BufferedOutputStream)>[[]]--><com.amaze.filemanager.filesystem.files.CryptUtil: java.security.Key getSecretKey()>[[]]--><android.security.keystore.KeyGenParameterSpec.Builder: android.security.keystore.KeyGenParameterSpec.Builder setRandomizedEncryptionRequired(boolean)>

You can add an if-then check like "If(Build.VERSION.SDK_INT >= 23)" when invoking this API to prevent compatibility issues.

Inspect the API call paths named in ZipService, CopyService, EncryptService, CryptUtil, Drawer, and MainActivity, focusing on the listed Android and cryptography APIs. Verify the app's minimum supported API level and add compatibility protection for each affected call. Done means the reported NoSuchMethodError paths are safe on supported Android versions.
