[Guida] Decompilare APP ANDROID (APK)

[Ma551m0]

con apktool (da terminale "apktool d framework-res.apk") al momento della ricompilazione mi viene fuori una lista esagerata di errori tutti relativi a file *.9.png

ne riporto una parte:

Operando in Linux, la decompilazione va a buon fine mentre durante la ricompilazione ottengo questi messaggi:

Spoiler:

apktool b framework-res I: Using Apktool 2.3.4 W: Could not find sources I: Checking whether resources has changed... I: Building resources... W: warning: string 'close' has no default translation. W: warning: string 'top_app_killed_message' has no default translation. W: warning: string 'top_app_killed_title' has no default translation. W: warning: string 'wfcSpnFormat' has no default translation. I: Building apk file... I: Copying unknown files/dir... I: Built apk...

a questo punto viene creato il nuovo apk da cui estraggo (con 7-zip) il file resources.arsc che vado a mettere nell'apk originario sostituendo quello già esistente. mi ritrovo quindi con il file framework-res.apk originario che da 30MB si è ridotto a 10MB (forse devo cambiare metodo di compressione?). vado a rimettere questo file in /system/framework e il telefono rimane bloccato alla schermata di avvio

Fai una prova.
Decompila il framework -res e, senza toccare nulla, prova a ricompilarlo.

Almeno sappiamo se l'errore sta nelle modifiche che vai a fare nelle png, nelle stringhe modificate oppure... c'è qualcosa di intrinseco al Programma.

ottimo consiglio!

ho provato a farlo su Linux e pare che vada tutto bene, durante la ricompilazione non campiono quegli errori di prima (".... has no default translation") ma semplicemente questo:

apktool b /home/marco/Scrivania/framework-res

I: Using Apktool 2.3.4
W: Could not find sources
I: Checking whether resources has changed...
I: Building apk file...
I: Copying unknown files/dir...
I: Built apk...

il problema è che anche con questo framework praticamente inalterato il telefono si pianta sull'animazione di avvio

Hai provato a "signarlo" dopo ricompilato?
Non è da escludere possa trattarsi di un problema di Firma.

questo mi rimane un po' più difficile in quanto non l'ho mai fatto (ho smanettato sempre e solo con il framework senza mai firmarlo).
più tardi ci provo e ti faccio sapere

per il momento, davvero grazie per la disponibilità

[marcol87]

purtroppo neanche firmandola riesco far partire il telefono
a questo punto alzo bandiera bianca
