How To Clear Cache On Android 15 To Stop Crashes [Solved]

Immediate Fix (Method 1): Clearing Individual App Cache

If a specific app keeps crashing to your home screen on Android 15, clearing its temporary data is the most effective solution. This process removes corrupted temporary files without deleting your personal login information or settings.

Avoid tapping “Clear storage” unless the crash persists. Clearing storage will reset the app entirely and delete your local data.

Technical Explanation: Why Android 15 Crashes to Desktop

Android 15 introduces updated ART (Android Runtime) optimizations that change how bytecode is compiled into machine code. When old cache files from Android 14 persist, the system may encounter “Instruction Set” mismatches.

These conflicts lead to memory access violations, causing the OS to force-close the app to protect system integrity. This is why a “Crash to Desktop” (CTD) occurs immediately upon launching resource-intensive applications.

Alternative Methods to Stop System Crashes

Method 2: Bulk Cache Clearing via ADB

For advanced users experiencing system-wide instability, you can use the Android Debug Bridge (ADB) to clear specific package caches. This is useful if the Settings app itself is unresponsive.

# Connect your device and run the following
adb shell pm trim-caches 999G
# This command requests the system to clear all unnecessary cache files

Ensure you have USB Debugging enabled in Developer Options before attempting this. This command forces the package manager to reclaim space by purging non-essential cache buffers.

Method 3: Resetting App Preferences

Sometimes the crash is caused by a permission conflict rather than a file error. Resetting app preferences restores default settings for all apps without deleting data.

After performing a reset, restart your device. This forces Android 15 to re-index system permissions and clear stuck background processes.
